depends on what you use it for. If you do a lot of internet based work or if you want to have millions of apps that do just about anything you can think of. then its the best thing for you instead of carrying around a heavy laptop.
There is no way to add anymore memory... What you see is what you get.. Makes no sence to me. There is talk of the new versions to have USB ports...But time will tell...
The new ones will have a USB port and also SD card ports. and I have a 16 GB Iphone and still have never filled it up even with all the apps I have. Grant it I don't have all my movies and music on it, but that's the point is a mobile version of your desktop so you don't have to store a shit ton of crap you rarely use.
Did not see it at the store. I carry most of my stuff on portable devices so that I can plug into anyones computer. Did not see the ports on the ipad... Neither did the sales person... OH well
