As I am not at all a hardware geek, I was pleasantly surprised to find I have the minimum specs. My Mac is going on six years old, so it was nice to know it isn't as old as I'd thought. What a nice price surprise as well. I never did get Leopard (the first time I skipped a version) - I went straight to Snow Leopard when it came out so cheap. I went against Apple advice and upgraded straight from Tiger. After initial speed increases, SL has seemed rather slow to me, making me wait regularly - even though SL was supposed to be a leaner and meaner version of Leopard. I am leery of putting Lion on top of that and giving myself even more headaches.
Anyway, I am sure a number of people here will try it quickly enough and I will read your feedback with interest.
