For what it's worth I'm loving my eris. No, it's not the monster powerhouse computer in your pocket that some devices are but it takes the place of all 3 mobile devices I used to carry and does it well at a very reasonable price.
My palm pilot (external brain / time waster (games) / book reader)
the comparison here vs iphone is all about the apps and both have what's needed. But in general I'm much more pro open source style platform so droid gets my vote there. I expect that apple will again closed system themselves into minority market share again like they did with Mac.
My mp3 player
I hated itunes because it REQUIRED me to learn IT's way of doing things. I already had a method of organization that worked just fine and I didn't like theirs so I bought a $45 player and 20$ SD card (instead of the $200 ipod) and had a media device that did everything I wanted and zero extra crud. I could (and did) upgrade the memory later to 2GB for a whopping $10.
My Phone
To quote a commercial I know, a phone is about the network. Verizon has better service in the areas I travel in. Verizon doesn't charge to call people in network (90% of my cell phone owning friends/family).
Other comments, I have friends who are apple freaks, and they wish their new iphone4 was more phone and less computer, apparently the reception is not as good. (and no I'm not talking about the death grip thing, they have the bumpers) My experience from the day I was shopping for my first pentium (75Mhz even woot! and a free upgrade to the new win95) is that buying an apple product will cost you noticeably more for the same functionality. My experience today isn't much different, though the gap has narrowed considerably.
