Hello all I thought I'd ask a couple of questions about this device just so I'm certain this will be what I need. This is my most important question: What's the deal with the IPad as an ebook reader? My main concern is getting many techincal books/journals that I already have in .pdf format on my PC over to the IPad. If that isn't possible this device will be worthless to me. Any thoughts? I've never used an ebook reader (they are simply too small for me) so I'm open to anything at this point. What really is the difference between a G3 model and the one with only Wi-Fi. Correct me if I'm wrong but doesn't the Wi-Fi work in, say, Starbucks where you can get the internet there? Whereas the G3 is used for both a phone and internet hookup anywhere...or am I missing something? The WiFI may very well be enough for me. At that point it's really just what memory I need. Any see a VERY good reason to go beyond the basic 16G? If so, let's hear what you have to say. Basically, I'm really hoping that this device will be for me. I haven't bought an Apple device in YEARS...I went PC (heh) about 11 years ago due to lack of software I need (basically more obscure engineering software that won't run on Macs) so getting back to my origins (Mac user back to 1984) will be nice change. Thanks for any help you can give! EDIT: Any concern of not having a USB port? Will that hinder my porting of .pdf files over to the IPad???
