PALM PRE IS LACKING BECAUSE OF THE FOLLOWING:
8 GB memory limit
No true apps - only webapps (so weak)
No voice and data at the same time (because of Sprint CDMA network)
No voice dialing (WTF)
No video recording (WTF?)
No voice memos (WTF)
No movie rentals (over the air or otherwise)
No visual Voicemail
No TV show rentals
No audiobook purchasing
No true app store (18 is a joke)
No console-quality games (like Resident Evil, Metal Gear, 1000's of others for iPhone)
No Peer to Peer games
No VoiceOver (the iPhone can read any screen to you, just like a Mac)
No native in-car integration (iPhone has this with dozens of cars)
No podcasts
Crippled copy/paste (for example - you can't cut or copy a webpage or any part of it)
No universal search (crippled - no e-mail search)
Tiny keyboard (iPhone landscape and portrait keyboards are bigger than Pre's real keyboard)
No auto wi-fi login (just jumps on any open network and remembers them all)
No 7.2 Mbps network speed
No Remote Wipe
No Find My Phone feature
Can't function as a Remote for the household stereo (Great for parties, especially with the iTunes DJ feature where people can request songs)
Weak battery life
More expensive than iPhone
Very scratchable screen
No oleophobic protective screen
No real music store (Apple can break the compatibility at any time and I don't want to take that chance)
No Voice Commands (control music playing by saying "Depeche Mode" for example)
No Compass
No multiple and customizable home screens like iPhone (Pre only has one screen)
No Parental Controls
No Video Editing
No onboard Ringtone Creation
No 5 person conference calls
No Webclips
