Very impressed overall. GoGear Vibe is compact, charges within 3 hrs from flat and has very good sound quality, even at the elevated volume levels I need when using it on my motorbike.
Colour screen and album art display are 2 nice points for me, and contrary to many other opinions, I find the navigation system simple if not perhaps entirely intuitive.
Video playback quality surprised me, in a good way, but the software provided in the box is rubbish. Free SMV converters are available, so I can't mark the unit down for that.
For the price I paid (£45 for 8GB version) I think it's great. I wasn't particularly enthusiastic about ipod because I've never been a fan of proprietary formats, so the fact that this can play every mainstream music format is a big plus. Strongly recommend
