1. I hate that the screen is the easiest thing to scratch in history.
2. I hate that when I transfer my music some song tags don't show at all and some show album artist rather than song artist. Some album art also mysteriously disappear despite all being embedded in the songs.
3. I hate that getting playlists to transfer and work on the device is a real mission.
4. I hate that when you play a video it takes ages to start up and stutters for first few seconds.
5. I obviously hate the media player.
6. I hate that you can't have a short cut on more than one desktop.
7. I hate that the phone aspect is so so so basic. The single ring tone was already annoying me enough but the poor phone element almost drove me mental when I went to Nigeria. You need to dial numbers starting with * to top up the phone but the N900 can't even do this so I would always have to take out my sim and put it in another phone just to top up. Super annoying.
