This has probably been asked lots before but I am new here. Any word/rumors on when an iPod Touch with a greater capacity than 16GB might be available? I have held out on buying one for probably as long as I can now and I think that the hard drive on my old 40GB iPod Photo is about to crash (lots of clicking noises and trouble syncing). Should I go ahead and get the 16GB or is there any chance of something larger coming out in the next six months????
