Good advice as usual, Alex.
There is a difference between the nightly builds that are in active development and the milestone releases. I have to say that 0.8 is very stable. It has an installer/uninstaller and keeps to itself in terms of playing nice with other software. 
Of course, it is still beta and there are bugs being reported. I definitely wouldn't recommend the nightly builds to anyone who isn't a programmer, but I've had no problems with the milestone versions.
