I've heard some rumors around that there is a possibility of a 5th Gen. ipod coming out in the summer sometime and was wondering if I should try to wait for that, or go ahead and buy a 4th gen?
If you want an iPod now, go ahead and get it. When 5th gen iPods come out, you might wish you had one of them instead, but think about it. 1st gen iPods are still perfectly good and usable, 4th gen ones will be for a long time too.
Unless you are making the money Jobs is, you may as well get what you can, and love it for as long as you can.. I still have my old style Dock connector Ipod, and don't have any interest in upgrading to the click wheel. I like my glowing buttons
