I've not really heard about it's sales performance in the Asian market (though I was reading something about China having an awesome $500 iPad killer that was doing really well.)
Over here there were plenty of ads on TV, Magazines, Papers, Instore, etc. Though, most models being $800 left the general population out from owning one.
lol, most people here buy apple products
android tablets get virtually no cover here execpt htc, samsung and SE products
the only people that I can see actually buying android tablets are computer enthusaists or people that actually play with android
otherwise, practically anywhere you go there is a 90% chance of seeing someone with some sort of iPhone, iPad or itouch on them
