No iPad for Tiger users?

[RAMd®d]

I'm betting you don't need a computer at all unless you want to sync, back up, and update your iPad, and as mentioned, add music and apps from your existing iTunes library.

Otherwise, as long as you have WiFi or 3G access, you can download music, apps, and other content, surf, and email all you want.

I assume you'll have WiFi at Mom's house. The 3G connection has a maximum size of 10MB per file for the 'Phone, and I bet it's the same for the 'Pad.
