Metro will also be appearing on 360 soon.
Gruber is nothing but a partisan hack and this proves it. No wonder he is held in high regard only by Apple enthusiasts.
Size, weight and battery life are three of the most important features of my iPad. Further, the non-fragmentation of the App Store is nice, a 1G iPad can run pretty much everything a 2G iPad can.
Why would I want to buy in to an ecosystem where developers are worrying about developing to the lowest common denominator? Would they consider optimizing their App for the 10% of their market that bought the Core i5 tablet vs for the ARM (in a total market size with 5 % of the tablet market)?
What benefit would you really see from a tablet with so much processing power? A I going to sacrifice all of that battery life so I can render video faster?
Ok, but what if they just let the tablet run all the apps that work on the desktop. Great. Now my overpowered tablet that has two hours of battery life and has a fan in it is running apps that aren't even optimized for a tablet form factor?
This does not bode well.
The iPad is popular largely because it's something completely different from what's already there. A big tablet with an i5 and three hours of battery life is pretty much the same as what already exists in the PC space.
Personally, I like power tablets. I got an android instead of an iPad (I gave away my iPad) because of the added functionality (usb in, hdni out). If I could have a windows tablet instead, I'd be a very happy camper.
Funny how when Apple released the iPad2 they talked up how much faster it was than than the iPad, but I didn't hear a whole bunch of people talking about worrying about the lowest common denominator then. Do you think the iPad3 will only be as fast as the iPad2? The iPhone5 as slow as the 3GS?
Perf deltas are something people get an understand pretty well.
