I'm the first to say that the screen on the xoom sux, even compare to my first gen iPad, but after using it for a while now, and the screen is actually not bad. In fact the color looks better than my iPad.
I would love to see the IPS screen on the Transformer, but looking at the picture of the transformer, the design to me looks like crap. Of course I wont pass judgement until I see it in person, but right now I'm loving the xoom. Also, looks like the Transformer will be delayed in the US, so oh well. I do like the design of the Acer Tab, but not sure how the screen will match up against the xoom. And there's the Toshiba... Ah, choices, LOL.
As for the browser; the problem I have with the stock browser is agent not staying (I know there's a way to do it, debug,root, etc.), but not much about crashing/FC's. I've switched to Dolphin HD now, and everything is all good. The latest update seems to fixed the constant crashing I've experienced. Now it's pretty much gone, in fact I haven't had any crashes since the update.
