Virtually anything You want, including X forwarding and any kind of virtual desktop finally *secure*, without sending passwords/traffic in the clear. Or, create encrypted tunnel between two machines, even if one is unreachable (behind NAT, that You don't control, so can't open ports), or even both unreachable, if You use common server in between, Your own (for example, home router with Tomato/OpenWRT/DD-WRT/whatever capable of real ssh), or one available as service (some of them free, google for it).
That was only to name few - it is hard to answer Your question, because it's like "I've got my first computer yesterday, please list neat things that I can do with it. I like playing soceer and basketball, and I'm listening to Heavy Metal". SSH is very wide topic, where only Your invention limit usage*.

*Trivia - just half of an hour ago, I used N900 to control CNC machine, via emc2 and linuxbox without monitor. And, of course, I was connected using SSH
Transfer files back and forth between Tablet and Desktop. Linux Gnome (or KDE) allows you to mount ssh filesystems by just typing the URL like sftp://root@192.168.0.2/home in Nautilus in location bar. This allows you to browse, see, edit,etc files from your tablet on your pc like files on your system. From Windows desktop, you can use winscp to access filesystem graphically.
Run any applications from your tablet on your PC, including graphical. ssh -X from Linux or using Xming or similar from Windows.
I Googled "what is x forwarding" and only got 5 hits.
I'm still trying to wrap my head around this concept.
Any good links would be really great if you've got them.
Thanks.
x forwarding allows you to run graphical applications from remote system (your tablet) on your Desktop. It runs the program on the remote system, but the graphical window opens on local PC.
If you are using Linux desktop, it is available native.
If you are using Windows, then you need Xming or similar program.
