It doesn't work "really poorly" nor... even poorly. Glitchy? All rotation on these devices is susceptible to glitching within certain apps, but not all... and if that's a problem that you wish to point to; start by pointing at your device you probably own.

I'm sitting here with an iPhone, Samsung Captivate & Nokia N900... all of them have an app or three that glitch on rotation. On the Captivate, it's Nimbuzz. I can slightly twist my wrist while placing it down. It will rotate or glitch into a rotate/unrotate frenzy every now-and-then. On the iPhone, for me it's textPlus - the ad will rotate first, then the app... and that's when it's on it's back and I tilt it slightly. On the N900, it was during my yesterday usage and trying to answer the damn phone while it was on a table and it got confused which orientation it should be and I almost missed a phone call.

Frustrating, yep. But to the point of a continued finger point and rant against that platform? No. Not unless you want to be petty... or unrealistic.
