I have not yet upgraded to Snow Leopard because of all the negative things about it. But I am wondering now, with all the application updates, 10.6.1 and other Apple updates, is it "safe" to upgrade to Snow Leopard. I am really looking forward to all the new features, but am happy with Leopard right now. Thanks!
10.5.8 is stable and everything works with it. Snow Leopard 10.6.1 is very far away from being robust and mature.
If you need a working machine to get things done, do NOT upgrade to Snow Leopard yet.
Snow Leopard currently sucks even more than Leopard sucked when it was released. Leopard became usable with the 10.5.2 update. The way it looks right now, Snow Leopard won't be really usable before the next couple of updates.
