    Add my voice to 'not buying until they make it useable'.

    Gloss screens are for idiots. It's as simple as that.



    I bought my wife a 27" iMac and she had to move her office, block part of a window to be able to use it. Yah, it was stupid to buy it. Not to mention that eye strain is a problem for everyone using them. Even if you don't think your hurting your eyes... You are. Sorry to have to break it to you. Unless you work in a cave with zero reflections... Gloss is a problem. The long term effects on your eyes are not healthy.

    Shouldn't have to wear sunglasses to use a computer.

    Sorry, didn't mean to upset you, it was a joke, sort of. Feng shui may be bunk but paying attention to it can net you many thousands of extra dollars when selling your home, at least around SoCal that is. As long as your address doesn't have a four in it.

    The 2.2GHz i7 really seems to hold up well against the iMac's desktop chips:



    Geekbench (Cinebench R11) scores:

    iMac 21" 2.5GHz i5 quad = 7000 (4.15)

    Macbook Pro 2.00GHz i7 = 8800 (4.6)

    iMac 27" 3.1GHz i5 quad = 8700 (5.15)

    Macbook Pro 2.20GHz i7 = 10200 (5.30)

    iMac 21" 2.8GHz i7 quad = 10800 (5.74)

    iMac 27" 3.4GHz i7 quad = 12000 (6.88)



    A couple of the numbers will be off as they are based on a range of scores but that seems to be roughly where they are coming in and they are sorted by the Cinebench scores, which actually indicate a real-world use as it renders a 3D image.



    The 2.8GHz i7 in the BTO 21.5" iMac seems to be a pretty good value chip. This is a 65W chip. If you are into rendering or encoding, you'd be better off with the 21" with the i7 upgrade, which isn't available in the entry 27". Perhaps they are offsetting the cost of the screen with the CPU here. Pretty smart as hardly anyone would care about i5/i7, they still go by GHz numbers.

    It used to be that the iMac was mostly if not entirely made up of mobile components, but it seems like they've been sneaking in desktop parts of a while.



    Yeah the iMacs use desktop CPUs, they maybe always have, I'm not sure but it seems mobile GPUs. Even the ones previously were mobile ones but not labelled as such. Makes sense as I don't think they could get a standard GPU in that chassis.



    In terms of performance, the 6750M is quite powerful and performs close to a desktop 5750. This is around 1/3 of the highest end desktop GPUs but some of them shove two GPUs in there.



    The 6970M in the highest iMac is double the 6750M so should be comparable to a desktop 5870, which is one of the highest-end single cards you get.

    "Apple has confirmed to Macworld that the new iMacs can be used as external displays via their Thunderbolt ports. However, to do so, you’ll need a Thunderbolt-equipped Mac, such as one of the early 2011 models of MacBook Pros."



    I'd expect that since the Thunderbolt ports externalise a PCI connection, you should be able to hook up an SSD outside the machine to use as a boot drive, which gives a better boost than a Vista pen drive, which is just a caching feature.



    I'd also expect it to allow manufacturers to built a video input device. Given the low latency, it's probably something companies like Elgato should look into.



    It's nice to see them using multiple Thunderbolt ports. That puts to bed the assumption that this would be a single port technology.

    OK, here's a question, and it may be very, very dumb. If so, I apologize.



    I'm considering selling my iMac 27" C2D, and getting one of these new ones at some point in the near future. If I do so, I obviously want to completely wipe this disk, and REALLY wipe it.



    How would I go about this?



    Again, thanks in advance.

    They have a 256GB Solid State Drive option for $600. Just wish they had a 128 GB SSD. That is what you need for OS and applications and desktop. It would be a lot more affordable. I wonder if an aftermarket SSD would be installable. They do seem to have 2 drive bays.



    You probably don't want to do this yourself (it's an enormous pain- and very prone to mistakes), but there's a third party solution:

    Let's see. Much faster CPUs, Dramatically faster GPUs, Addition of Thunderbolt port which will blow away any other external transfer mechanism. Sure, just a 'mild' refresh according to Daharder.

    I use Logic Pro a lot and need to decide if the i7 is worth the upgrade. Also, is it strange that the 15" and 17" MBPs come with i7 default and the iMacs are an additional updgrade? is there any particular reason for that?



    Anything a bit more in depth than "they're faster" would be tremendously appreciated.



    For a CPU-intensive app like Logic, I'd definitely go with the i7. For $200 (roughly 10% of the price of the bare-bones machine), you get 10% higher clock speed and twice the number of cores. No brainer. Then add $100 for 4 GB more RAM and you're set.

    Unlike some previous models, adding RAM to the current iMac is trivial. You don't have to 'get into the guts' - there's a separate port and it's very easy to get to.

    Weren't they saying how wonderful it would be because you could plug in a flash pendrive externally and it would speed up processing as a RAM cache? I never heard of anyone actually using it.



    Any relevance to thunderbolt here? I.e., plug in a 10GB dongle and see your iMac speed up?



    Actually, you can get a better hybrid drive from Seagate. The memory is built into the drive itself and doesn't require OS intervention. In my experience, it helps, but isn't really comparable to a real SSD.



    The problem with the above solution is that it's limited by USB speeds and requires the OS to get involved - which adds overhead.

    That way if USB 3 HDD become commonplace as I suspect they will I can plug them into the TB slot using an adaptor and at least be able to get the USB 3 transfer speed.



    It's coming. There will be adapters which allow you to plug a USB 3 device into a TB port.

    That is the conventional logic, but may no longer apply. Thunderbird is faster than the SSD, so even putting the SSD into an external box may make sense. In fact, one great solution might be to buy an external TB RAID box and add multiple SSD drives (since there will be several, you can choose smaller, less expensive ones). This solution should be even faster than an internal SSD.

    1) There is a help area on this site and others specifically for technical issues that make better use of these questions for yourself and others.



    2) Restart with the included DVD. Run Disk Utility, Format the drive, and zero it out as many times as you wish.

    The reflective screen issue is no less annoying than continued use of C2D processors in Mac minis, no backlit keyboards in MacBook Airs, crummy integrated GPUs in 13" MacBook Pros, no numeric keypad in the wireless keyboards, no xMac, etc.



    The answer you seek is to buy enough stock so that what you think makes a difference and go to Apple shareholder meetings. That's the best way to get what you want from companies.



    Barring that, you can start a Facebook page and get everyone who hates glossy screens on iMacs to LIKE you. Use it to set an event date and parade in the streets outside Steve Jobs home like masses of Egyptians did for days on end. Then if you don't get tear-gassed and shot by Pixar green army men snipers, you have a chance of changing the world.

    Matte screen users have options. You can buy a Mac Pro or a Mac Mini and bring your own monitor.



    Or you do what I do - keep using your old white iMac until it dies and then switch to Linux or Win 7.

    Apple couldn't care less about games.



    ALTERNATE REPLY:



    So now that we finally have a top-level GPU in the iMac instead of mid-level, you decide to whine about something else to satiate your need to complain? Good going.

    300GB 15k sas drive = $269.99

    240GB SSD drive = $649.99

    How much is an SAS controller card and which Mac Pro do you have it installed in? Cheap I tell you cheap!

    What are the relative Input/Output operations per drive? A consumer doesn't care about IOPS

    but an Enterprise customer would care and a 269 dollar SAS driver isn't quite the bargain if

    the performance cannot match SSD in crucial areas.

    It's not about getting the absolute best performance. Yes SSD is fastest - it's also the most expensive. SAS drives are cheap now, Apple should be offering them standard on the new Macs as they're better than Sata.

    No but I didn't miss the part where you said SAS is cheap either. Aren't most of those controllers like a thousand dollars? The drive in a consumer All-in-one which is mostly mobile parts should have an expensive RAID set up? Right... What are you smoking?

    I like SAS because it offers dual ported drives, logic in the chipset (low CPU util) and bidirectional performance but it's still a bit spendy.



    I think a SSD cache in front of larger but low spinning disk (5400rpm) is the future.
