I updated my 2007 install up to 2010 Beta. Three years without a reinstall. On another CPU (2009) Tex and crew managed to upgrade the gcc core which many believed was not possible. If you install 2010 final, I can pretty much say (based on my experience so far) that a reinstall will not be necessary, for years. You ask, will you have to reinstall 2011? Maybe.... don't know. But go with another distro? Reinstall every 6 Months, that's how most distros work, but not this one. Go with what works for you, really, even if it's windows7. Stick with us, and we will shoot it straight, as best we can. You won't be disappointed, you might even join us in the sandbox.
