I've generally not been too unhappy with the way utorrent's developed so far, and I certainly don't agree with all those people who insist it's turned completely crap and only use 1.8 or whatever, so normally I'm happy to keep upgrading to the latest version. I think, however, I'm going to stop and just stick with what I'm currently using (3.1.3) now, because I can't be doing with this. Ads I can accept to an extent, but as soon as they start impacting on the user experience - and adding 'sponsored torrents' to your torrent list definitely does that - it's too much for me.
So yeah, I for one am not impressed.
