no one will pay more than that for a less functioning OS
. Anyway, there is no point in buying a compressed OS like iOS or RT
Apparently you have no clue what Windows RT actually is. It is a full featured Windows and matches x86 Windows feature by feature. It is simply the very same Windows compiled for ARM processors. Comparing it to iOS is just stupid. What ARM devices are lacking is the ability to run x86 code. This is not a Windows RT issue.
Having this out of the way I am getting to my real point of this post. Intel processors and in particular Baytrail are far behind, when it comes to multimedia/GPU performance (games etc.). Being mainly for consumption devices, customers will just pick the SoC with best performance, which at the same time minimize power consumption.
Once you are at the point, that you decided to not need legacy desktop programs on your tablet you can make the above choice - getting the best SoC for your needs. We can be lucky, that we still have this choice with Windows RT. It would be terrible for the Windows ecosystem, if the best mobile SoCs are only available for competing ecosystems.
iPad 4 was 1.5 pounds, Asus T100 is slightly over 2 pounds.
iPad air is 1 pound, while having a significantly higher screen resolution. At the same time A7 outclasses Baytrail in performance and power by a significant margin. A7 is a very good showcase of what ARM architecure is capable of. Recently released Tegra K1 seems to be a good match for Apples next iteration, the A8.
