To be honest, I'm not entirely sure but I can tell you that the only two ASUS products I've ever had (both of which were Android tablets) had great good memory, great speed and just preformed outstandingly their entire lives. Of course, the kicker is that their lives were very, very short.
Both tablets stopped working inside 6 months (which is annoying, given the 135 buck price tag for each) - one of them just quit turning on. No rhyme or reason to it. The other stopped recognizing the charger and eventually just lost power and never did come back on. I think it's fine, actually, other than it's inability to charge and I wish I knew how to fix it because if that hadn't happened, it was a darn fine bit of tech and did just what I needed it to do.
I've only used an ASUS tablet once, during a campaign rally, and it preformed well, too. It was mid-summer in the Midwest, hot as all get out, and the laptop stayed cool and kept on doing it's thing without external cooling or anything.
