I'm considering buying the 3G iPad if it comes out while I'm on vacation. I'll be in a city with a Best Buy for part of my trip. But my main computer that I currently sync my iPhone with is my desktop, which won't be coming with me. I also understand that you need to connect to iTunes before you can use the iPad. Any down side to just syncing with a copy of iTunes on my laptop? I'll probably have to wait until I return before I can download the apps. Any other downsides?
