Java isn't developed by apple. They stopped supplying it as part of the OSX installation, in the same way as they don't provide other third party software, such as the flash plug in. It's a third party software, and as it,s no longer essential to the OS it's not going to be included as part of the standard installation.
I think their judgement in leaving java behind has now been justified...
I don't understand what is 'pro' about an optical drive. What do you need it for? I haven't bought physical software installation disks for over two years now, what use does it serve? I'm sure there will be a peripheral available for those that need one, but i can't imagine why anyone would need this in a portable device.
I guess in losing an optical drive, there would be plenty of scope for slimming the iMac down. Most of the weight is in the lcd display though, so guess they wouldn't be too much lighter. Heat has always been an issue for me, the 27inch can run very hot, but the screen glare 'issue' has never been a factor, simply position the iMac correctly in a properly lit room, no issue at all.
Very excited for a revised form factor and an even more powerful top end 27" bto...
The point is that the device is capable of 4G - that is the claim made, that is the product sold. It works just fine on 3G and on your local wi-fi. If you were to travel to a 4G area, you would get 4G - that is the claim made by the product, and the claim is true.
Because 4G is coming on line and being developed now. Normally people complain when 'x' technology isn't included, even though it's not been globally adopted as a standard. This time Apple are ahead of the game. No complaint to be had here. It's not even hidden in the small print- it states clearly that you can connect to 4G where 4G is available. Apple makes no claim about the availability of 4G locally.
