Rants:
-Syncing to the Mac is horrible, Google apps has very limited support with Address Book, iCal and iTunes (yes you can do it but it's not easy and not natively supported)
-It crashes a lot, sometimes its just apps crashing, others, the whole phone just goes black and needs the battery removed
-The pullout keyboard is horrible (flat keys, off center) and the on screen keyboards aren't quick enough. I can type twice as fast as it can capture so I get a lot of missed letters
-Visual Voicemail costs extra (free on iPhone)
-Limited video support, only supports one codec and getting high bitrate's is a pain. As an animator I need high quality video!!
-The widget are not universally sized/placed. For example, Google search widget is short and top justified, mp3 widget is average size and center justified. Or compare Weather Channel widget size to Calendar widget size, these should be the exact same.
-Only 3 screens available for widgets/apps
-Edit: the sound volumes are all synced. I want my messaging (DROOOOID), ringtone, and alarm clock at different volumes. I didn't wake up the other morning because my ringtone was low but I wanted my alarm loud.
Raves:
-Nice screen resolution
-Google Navigator is awesome (except the Latitude doesn't seem to accurate reflect where my friends are)
-Widgets, love em!
