Lol. Tech support guys are always clueless. The real problem is that third party companies aren't supporting ARM yet because the market isn't there. Whether or not tech support understands that is inconsequential.

And if/when companies do support it, it'll probably be a marketing gimmick to make you buy a newer product. (The inkjet printer I bought last year had a variant with iPad printing support for $20 more).
Anyway, why stick with ASUS? I went into a Microsoft store in Santa Clara where every single product they were showcasing was touch screen with Windows 8 (Surface, tablets, laptops, including ones made by ASUS, Samsung, Sony, Acer, Lenovo, etc.) I have to say, the ASUS dock keyboards were some of the worst keyboards I tried. The MS Surface hard keyboard is better but flipping open the kickstand is not as convenient as the ASUS netbook-style dock, plus the Surface has really square edges. My favourite product was not any tablet, but actually a touchscreen laptop - the Acer Aspire S7 (i7, 13.3" with a beautiful 1080p screen - not sure if IPS but it looked like it). My favourite tablet was probably a Samsung 11". Good size, good design, and it had a bluetooth keyboard, but again not as convenient as the ASUS dock.
Overall I feel like none of today's tablets have everything to my satisfaction. Neither does my TF101 (and its woefully unergonomic keyboard), but if I'm going to spend money to upgrade, I'm going to wait until someone gets it right. The laptop is the only thing that's worth buying IMO.
