70% Internet (be it forums, research, news, buying stuff, check weather, tickets, reviews etc....)
5% Emails
1% Downloading/uploading photos
0.5% Ripping my own DVDs/CDs
15% Listening to music
0.5% Games
2% Synching my iphone/itunes/calendar with outlook
6% Watching movies/series - though I have a nice big HD tv in lounge it's sometimes nice to be in your room.
I thought I'd make up some completely non quantified figures - but if I'm honest it's probably about right.
