i have one. Its nice. Touchscreen is cool. But i think i should have gone for the nokia n95. But thats just me personally!
Dont believe what you read in reviews about the camera on the samsung, its absolutely fine and the pictures are sharp. There are just little thinks that are a bit annoying like the fact theres no voice dial (which proves a problem with my carkit), when i set the alarm in the morning, the snooze never seems to work and it seems to freeze sometimes when you try to turn off the alarm and hit snooze.
Diary could be a little better. It really depends on what you are looking for in a phone. If you are just looking for a general all rounder with media player, camera and makes call, its grand. If you want to customize it a little more or want wi-fi etc. Forget about it!
