I like my 4Gb nano, and its battery life is great (due to lack of hard-drive), best mp3 player I had to date.
But if you are looking for more than music, I think it is worth waiting for other portables to come in the market, then you'll get a chance to see if there is any better alternative, or buy an iPod at the reduced price as it should theoretically go down. Either way is better than getting it now.
