"You can tell that the processor is fast, but the UI still has a jerky quality to it -- it's not totally fluid. We'd say that's more of an Android thing, though." **Quoted directly from engadet's preview. "Don’t get me wrong: the Droid X is a delight to use. But at times, the hypothetical finish feels a little rougher than it should, and it’s lacking a certain refinement — in how it switches between screens, in how it responds to the touch — that one sees in an iPhone or even iPod." Quoted from Zdnet.com's preview. I have hopes that the phone is nice and fluid. I remember the droid when it first came out was lagggggggggyyy, especially on the home screens. Lets hope the X is not.
