You have another choice as well: run XCSoar in simulator mode at home

Don't want to mess up your current configuration? Download the Windows
version and run it on your PC (it also runs just fine under Wine on a
Linux box) and then, if you decide you prefer the configuration you've
set up there, copy it over to the rig you fly with.

FYI: There is a native port of XCSoar for Linux (and OSX).
There is no need to muck around with Wine.

If you're running Debian/Ubuntu you can even do a "sudo apt-get install xcsoar" from the command line and be up and running within minutes (although the version will be a little dated). Then just download a map and waypoint file and you're good to go.
