Can I use an iPad effectively without a computer to dock it to? I'm interested in buying an iPad, but I'm trying to understand what the implications are of not synchronise/docking it with a computer. I only have Linux (Ubuntu) machines these days; I have nothing running Windows or MacOS. As far as I understand, there is no official support for Linux (I am aware of libimobiledevice, but would like not to rely on it).

I'm used to my HTC Desire, which is able to synchronise most things I care about (IMAP, Google Mail, Google Calendar being three key ones) over the air, and I'd like to work this way with the iPad. When folks speak about the iPad, there seems to be a lot of talk of docking it with the computer, but I'm not clear why this would be needed/desirable. Can iPad apps typically sync over the air? I've seen reference to MobileMe, but that implies that this facility is not built in and may cost extra.

What do I lose by not docking/syncing the iPad to a computer? Can I do that - buy it and use it indefinitely without docking it? Will I lose any major functionality?

Thanks.
If you get a 3G iPad, I think the 3G data plan has to be activated through iTunes.  If you get Wi-Fi-only iPad, this isn't an issue.

Note that you can probably get by if you have a friend with a Mac or PC who will let you sync once in a while for these rare needs.

Syncing is also useful for these needs:


Backup
Transferring photos (although you can e-mail them instead)
Syncing calendar and contacts
Getting music, videos, and books from iTunes Music Store (you can d/l songs over the air, but I think the other media types have to be done through desktop)


But if you don't need those areas of functionality (and many people won't), then you won't miss syncing.  Basically, if you don't expect to use Apple's built-in apps, you won't need sync.

MobileMe is really only useful if you have a Mac or PC.  It makes it easy to sync calendar and contacts across multiple machines over the air.  A few third-party apps use it as well, but not many.

Third-party apps typically sync over the air, because Apple's sync is not very open to third-party developers.

FWIW, since getting my iPad, the only time I turn on my MacBook is when I want to backup/sync purchases or charge my iPad.  I'm not saying that the iPad is a complete substitute for a laptop, but it is definitely a useful device all by itself.
