Hi, I agree with the other positive reviews here, this device is absolutely brilliant as a music player, organiser....even a mini-computer with the right apps!
However, don't believe the title...this is still 2nd Gen hardware - a point I've just learned the hard way. The only 3rd gen ipod touches are the 32 and 64GB versions. The 8GB is still 2nd Gen, and the recent iOS4 updates comfirm that, as it's NOT capable of multi-tasking with the update.
So, if you're looking for the latest iPod Touch hardware, that will do most of what the iPhone 3gS and 4 can do, you'll have to go for the larger capacity version.
Still for 140 pounds, this is a great entry level iPod, that will give you the Apple iDevice experience for a fraction of the cost of the iPhone. If multi-tasking doesn't bother you (and let's be fair, it didn't for most people up until a few months ago), then I heartily recommend it.
