My only annoyance right now is that despite M-Web saying that throttling is worse than shaping, the fact is that the M-Web service level right now is FAR from ideal. Downloads over HTTP are probably running at 60-70% of my line speed, and only over multiple threads, with single threads being probably closer to 30% of line speed. Streaming is incredibly poor *most* of the time (although sometimes it works fine) with YouTube and Game Trailers being particularly good examples. FORGET trying to download over any other service (BitTorrent, and so on) - there you're looking at maybe only 10-15% of line speed.
I would like to point out that my gripes generally revolve around international access. I don't use the local web all that much.
Oh and this is a 4mb/s Uncapped account.
