It has been rooted. But there are caveats. First, some apps that need root work...and some don't. Second, the bootloader hasn't been unlocked yet....so custom recoveries and ROMs aren't possible. Third, there's no "n0oB" method to root. No "one-click" or app/script method yet. It's still all manual (and VERY touchy) ADB work.
I'm waiting until it's all sorted out. Honestly, I haven't seen as compelling of a reason to root the A200 as I have with phones. Not being able to remove bloatware with Titanium Backup is a little bummer, but not a deal breaker. There's not that much useless bloatware.
