Some of the phones I have had were the krazer, the razr, samsung t439(Free Phone from Tmobile that sucked) and a sony ericsson t300. The k800i beats out all of these phones 10x and plus.

It's not huge, just not as pleasantly pocket-friendly as the K750 / W800 / W810: Since the K800 is a 3G phone for Europe and Asia, and Sony Ericsson isn't doing 3G phones for the U.S. just yet ...
