MacWorld has a pretty decent review of the HP Touch Pad. Seems like a pretty decent entry by HP into the tabled market. However I wanted to highlight one piece from the review:
The TouchPad’s specs are state of the art, right down to the dual-core Snapdragon processor that powers it. Yet at times I found the TouchPad puzzlingly sluggish. (I had the same complaint when I used the dual-core Motorola Xoom Android tablet, to be fair.) Sometimes I think one of the most important achievements of Apple’s iOS development team is completely overlooked by most reviewers: the fact that on iOS devices, when you move your finger, the on-screen objects under your finger move along with it. No lag, no judder of dropped frames, just a pure illusion that you’re physically manipulating an object. Almost every time I have tried a new Android phone or tablet—and when I tried the TouchPad—I am surprised to find that the interface just isn’t as responsive as Apple’s.
This is something I have observed as well with Android devices. Most recently I noticed this with the Verizon Thunderbolt. There’s something the Apple is doing different which gives their devices much better touch responsiveness. Odd that companies with millions of R&D dollars have not been replicate that aspect of the Apple devices.
