I did not compare with an iPad next to it - although I could have, since they have ipads at the VZW store. But the screen was extremely crisp and vibrant. I found the 7" screen to be the perfect size. Huge in terms of screen real estate compared with a phone; but still a compromise from the ipad size which is only slightly smaller than the tablet pc I have. But more important for me was the weight of the Tab, and the feel of it in my hand. You could easily hold that and read stuff or work with it for a long time. The ipad is close to twice the weight.
The touch interface on the tab was just as responsive as the droid - and just as responsive as the ipads that I have used. Plus I like the comfortable feel of having the four menu buttons available. I have learned that the tab is capable of being rooted, so who knows what fun stuff will come next. AND there is an ability to make "non-tablet" apps expand to the full screen, instead of doing the black bar thing. I am not sure if that is available for the ipad.
Some have said "its only 3 inches bigger than my phone, why would I want that? Well, for me those three inches make a huge difference in viewing web pages. It becomes an extremely useful internet device that is light and can be easily carried around.
I want one!
