As I posted in another thread, I went to the local Apple store with a friend so he could buy an Air. This motivated me to buy the OS-X Lion upgrade for my MacBook Pro.
The upgrade went well, no issues at all. Took a long time, its a big download.
Most of the changes, bugfixes and improvements are subtle. One is huge:
Lion makes window scrolling work like it does on IOS devices. This is backwards from the way Macs, Windows and Linux boxes have worked. This goes back to the original 1984 Mac release, early Windows releases, and Linux from day one.
There is a user preference, you can switch it "back" or you can try to relearn motor skills that are decades old.
I thought that I'd be looking for the preference control panel instantly. But I did not. I decided to give it a try, and see if this heresy has potential.
I think it does. I've only been using it for 20 or so hours, but its OK, seems natural already. I would have bet big bucks that this was a bad idea, before I tried it.
I did the same, and especially because I use a trackpad rather than a mouse it became completely natural very quickly. Now, when I'm on a system that has "old style" scrolling, it seems weird and unintuitive.
