Hey all- So here's the deal: I want to plunk down for a 16GB iTouch. I feel like it's basically the greatest product ever created by Apple (possibly by anyone). When I get back to school on the 11th I want to place my order for it, with custom engraving etc. My question is, would it be best to wait until after MacWorld San Fran (the 18th) to place my order? Is there any chance they release any sort of updated (hardware-wise) iTouch? What would you guys do?
