Which Ipod Touch Would you get and more ...

So I'm planning on getting an Ipod touch and have no real experience with Ipods. I read some reveiws and for the 3rd generation touch and it said the 32 gb and 64 gb versions have more processing power than the 8 gb version. So I am going to get either the 32 gb or 64 gb version.I am going to use it to watch movies and airplanes and whatnot so the 64 gb version would not just be a waste of space. The $$$ difference between the 2 is significant to me though. If I just got the 32 gb version is there a way to transfer files to it from a thumb drive or other memory cards (sd cards??) without using a computer? Again I have no experience using Ipods so I'm not sure what kind of input sources it can use. Thanks for the help!Which Ipod Touch Would you get and more ...
The only way you'll be able to transfer stuff to it is with Itunes. It does, however have wifi, so you can hook up to the internet and download stuff directly from the itunes store. Think about the space: 32 gigs will hold almost 20 full length movies, you can always swap them out before your trips. I ended up getting the 64 gig solely because the walmart near me didn't have any 32 gigs. I love it, and it is nice to have my entire music collection on there as I love to just have it hooked up to my stereo all the time, but even 64 gigs isn't really enough. Either way, you'll be happy, but 64 gigs is not big enough to justify the price difference as it is still not enough room...
