I've had a couple of weeks playing around with Mint now. It's entirely rejuvenated my aging laptop's performance.
Apart from struggling to get my printer to work and failing to find a genuinely useful replacement for Windows LiveWriter-- for the blogorrhea -- I'm not doing too badly with the migration from Windows.
My eleven year old daughter's been so enthused that she borrowed the USB I installed from and has got our desktop Mint-ed too. She's been playing with Kturtle endlessly.
