    That last reason is why I do not buy cellular for the Apple Watch or iPads.  The thought of having to pay an extra $10 a month per device makes no sense to me.  Unless you are on the road a lot and will be using cellular on those devices, it just isn't worth it. The same thing would be true for a Mac with a cellular modem.  If you are mostly using the device at home with Wifi connection, paying for the cellular service is waste of money.
    FWIW, the personal hotspot on the iPhone works well.  For both Macs and PCs!
    I find the £5 a month fee for cellular on my watch is liberating. 

    Just last night I was out jogging. AirPods Pro + Apple Watch cellular is a dream match.

    I frequently leave my iPhone at home now. I can still be contacted in an emergency and use useful features like Apple Pay, whilst not being distracted by my phone.

    I think people don’t realise how much they stare at their phone whilst out for dinner, etc. It’s great.

    I hope that some of the limits of Apole Silicon will be lifted:

    1. no target disk mode

    2. more / expandable ram

    3. 3rd party graphics hardware 

    I don't see any of these being addressed in the next hardware release except for maybe discreet graphics.   Apples processors get some of their huge advantage from having in package RAM.   This is similar to high end GPU's and compute chips using HBM in package to increase performance.   I wouldn't doubt if Apple take several avenues to lowering the access times to RAM and cache as improvements here allow for more cores and higher performance with out massive crank ups in processor clock speed.   Basically going out to DIMM for memory access is just too slow these days, unless you go to very wide memory systems.   Since I'm not expecting a Mac Pro class chip I'm not seeing support for DIMMS either.

    Rather what I would like ot see as 3 very important improvements are these:
    1. Full support for high speed M.2 modules.   This must be beyond what the processor will be directly accessing and is expansion support.   Yeah I know Apple doesn't care about storage expansion but we can hope.
    2. Improved I/O ports and more of them.   This would allow for machines more closely optimized for the desktop and working laptops.
    3. Improved integrated GPU's.   Lets face it Apple has a lot of space they ca dedicate to a GPU.   However the problem with all APU graphics performance wise is memory so they will need to address that.   DDR5 might be the path they take but it would be really neat to see HBM type memory in package to actually permit the chip to work well.   In any event better GPU support is closely tied to improved memory systems.

    You are dead wrong, as always.  Look at all benchmark results and discrete graphics continues to blow away the M1.  Apple is not going to release an iMac, MacBook Pro 16, or Mac Pro with the inferior integrated graphics, even on the M1.  The 16GB RAM limit of the M1 is embarrassing, and it is a big deal.  Large graphics files would choke on it.  Especially embarrassing when the previous Intel models had more features than the M1 models.  But of course you hate Apple as evidenced in all your comments.

    This is garbage, there is nothing embarrassing about M1.   Apple debuted it in its lowest end machines and int hat regard it literally blows away anything in the price range.    The M1 is the best tech Apple had at the time to put into something like the Mac Book Air.   Feel free to offer up another passively cooled, low end laptop, that does better.

    IMO, I don't see 16GB of RAM / 2TB SSD an issue for the three models of devices Apple released.  I think the Mac Mini, MBA and entry MBP are focused at people with light needs, like web browsing, office apps, etc.  I don't think these kind of users will have an issue with these specs.

    My M1 Air is with me because it is a better device than an iPad for my mobile needs.   For performance I have a large screen Linux machine in a desktop format.   MacQuadra's comments just strike me as ignorant as everybody knows that every M1 released to date is a low end machine.   This Air is incredibly good and I can't imagine that there is much at all that competes with it.

    Now that doesn't mean the M1 Air is perfect but it isn't like I'm going to complain much as it is an enjoyable machine to use right now.

    First, thanks for mentioning the GPU mystery as I have been pointing out in my comments for some time. You left out part of the mystery which is that if Apple continues to use AMD GPUs on Apple Silicon Macs, who writes the drivers? GPU drivers are highly optimized and are not as portable to a new CPU architecture as application code. AMD does need to port to ARM in any case (and likely already supports it) but the Apple Silicon CPUs are ARM variants and will need custom optimizations. Then there is Apple's investment into GPU design. The use of an AMD GPU on a M1+ or M2 computer would feel like a step backwards compared to the M1 which was all Apple. If I had to bet, I would guess that Apple will announce a new GPU to go along with the new Apple Silicon processor. Whether it can compete with current desktop GPUs is anyone's guess. Thus far Apple has come no where close to the performance of a RX 6000 series GPU (or RTX 3000 series) gaming GPU.

    However, there is another mystery. The M1 had the RAM built into the chip along with the CPU and GPU. This was a surprise when Apple Silicon was announced. No other system CPU vendor does this to my knowledge. The up side is that this allows the CPU to talk to the RAM more efficiently. The down side is that you are limited to the amount of RAM Apple built into the package. Will the M1+ have the RAM built in or will it be external and upgradable? Will it be a combination with some high speed RAM built in as another level of cache?

    1. Yeah. It is curious why they haven't had cellular modem options for their laptops.

    [SNIP]
    One doesn't need cellular functionality in the laptops as long as your iPhone/smartphone has a mobile hotspot function and this of course requires you to have that service and that device. You could also use an external mobile hotspot if you prefer not to use your smartphone. Having optional cellular functionality is like including a CD burner, most people don't want it and there is an external option. Don't carry over a mentality of a typical Windows maker.
