No surprise here, but I do hope the UK soon improves rights for us consumers!
Whether that should include sale of legally owned MP3's? I don't know, but there seems to me there is no reason they shouldn't.
I think copying/streaming & format shifting (i.e. changing from WMV to AVI/MP4 etc..) of legally obtained media for personal use should be enshrined in law to protect those of us who use current technology to the full and those in the future that won't even realize they are violating copyrights.
There are many of us who would purchase online often if it didn't restrict where we can play what we purchased, I for one only buy non-DRM music online.
I am sure I would spend a couple of hundred sterling more each year on film/tv/music if I could get DRM free copies of everything I wanted..
