My son has an 8gb 4th gen iPod Touch that is out of storage space. It really slows it down too when running App Store updates because it can't download and update more than one at a time. I was thinking of getting him a 32gb model, but the new 5th gen next month is $299. I see on the Apple Refurb site that the same 4th gen model that he has, but with 32gb, is $209. Space being equal of course, is it a mistake to get the soon-to-be previous gen? Or throw down the extra 45% and get the new one? Thanks!
