would it be possible to trade in my iPod Nano for some credit toward an iPod touch? I want the 8GB iTouch, and it costs $299.99 plus tax, for a total of $320. Now, when I get paid, and add that to the rest of my amassed wealth, I will have accumulated a grand total of $296.87. I won't get paid again for another two weeks, but I don't think i can wait that long! But then it hit me.....since I'm so close to having enough money....what if I were to trade in my iPod Nano to put a dent in the cost? Is it possible? How much of a dent will it put in the cost? If it takes a low as $50 off of the iTouch cost, I will be one happy camper. Also, I've read numerous reviews saying that the iPod Touch has no notes application, no GPS, no email, and the inability to edit events from the calender on the device itself, but all these reviews are old. Can anyone tell me, as of RIGHT NOW, can the iPod Touch do any or all of these things? This is extremely important to me, as I actually want a PDA. I'd get an iPhone but i can't afford the extra $20/month on my current ATT bill. Thanks!
