I read the Apple site about Lion, says to use the Mac App Store, which is only available in 10.6 I have 10.5 and I'm not going to go buy a $30 disc, and instantly spend $30 again on Lion. Any ideas?
Sorry I never felt like I wanted snow leopard, never saw anything I wanted to upgrade for.
SL has some amazing under the hood enhancements. Grand Central Dispatch is one of them. A lack of end user changes does not mean nothing was changed!
SL did a ton of work under the hood with 64 bit also. It is definitely worth it. Lion just seems substantial because it is a lot of front end changes. It probably also seem substantial because they took a risk with a lot of what they did!
You could login at a friends with your Account, purchase it and download or use his copy to make a USB Install Drive of Lion.
Windows Ultimate is $400NZD. You'd be spending $60. I'd spend $60 to get Lion if I were you!
For the common end user, Snow Leopard meant almost zero changes over Leopard. The performance was just "a little bit" better. I can understand why the OP decided not to go with Snow Leopard.
