erm, sadly not - the game calls home after every activation and decrements the amount you're allowed by one - this means uninstalling/ reinstalling doesn't use another one of the three your allowed, but Hardware upgrades (EA won't say what will require another activation), re-install of Windows all will.
Personally, I upgrade regularly and re-install frequently, and I'm not adverse to buying games (like the new Special Shiny Ed of 'Clear Sky' ), but i'm stearing clear of Spore as well.
