From Tiger to 10.6.2, all my upgrades went seamlessly. But I wasn't happy with Snow Leopard memory usage or Safari flash player running the cpu fans so hard.
Decided to do a clean install of SL, after I learned you can do it with only an upgrade DVD.
Everything is working better now !
Good for Apple for all those seamless upgrades ! But at some point, a clean install is the only way to go.
