Apps is a huge argument for the iPhone or even Android above the RT. MS and their fans are saying just wait we will catch up but, will they? The Windows phone is doing poorly in the market and App development is slow compared to the competition, this could be a foreshadowing of RT's success. There are no real major programs on the RT except Office (at least parts of it) and it is a poor port from the computer version that is all but useless when using the RT as a tablet. All major companies are writing for iPhone and some Android. Based on this there is a very strong case that the RT will never gain traction and will remain a nitch player.

I also agree with the analysis that a wide screen is a very poor choice for a pad device. It is very clumsy to use, this was known from some of the Android pads that tried it. 3:4 is the optimal large pad. I have found that the 9:15 does work on a 7" pad because the small size still makes it manageable.
