If I can fit a 24" screen in my pocket I would. In this case, bigger is better for me. My eyesight is good but that doesn't mean I like to strain them while viewing tiny lettering (regardless of how crisp they are). I played with the iPhone 4 a few weeks ago and walked away unimpressed. The screen up close is crisp yes, but laughably small. And after a certain pixel density the human eyes can't tell the difference anyway. To me it looked no crisper than the regular droid. Compared to the X the text crispness was negligible at normal viewing distances, however the X killed it in overall comfort and color reproduction. I'd much rather view the web, a picture, or a video on the X.
The iPhone 4 resolution, IMO, was wasted on such a small screen. They could have easily gone 4 inches and retained the same res. and no one would be able to tell the difference. Instead they cheaped out and went smaller. Now in light of the competition, Jobs had to save face and say no one will buy a large screen. Yeah sure.
