Apple really ruined my productivity with Lion.
If I had wanted iOS i would have bought an iPad not an iMac.
I totally agree. After spending two months with Lion, I'm back to Snow Leopard.
Spaces/Exposé works much better for me than Mission Control. I especially don't like that the menu bar and background moves when you switch to a different space in Lion. The animation gives me a headache as I often switch spaces several times per minute, and brings nothing of value. With Snow Leopard, you can remove the animation completely, making cmd+number switches instant. And when you have a static TV window open in Lion, switching to a new space "closes" and "reopens" the window. In Snow Leopard, a TV window is static during a space switch, just like the menu bar and desktop. Much better, for me at least.
Address Book in Lion takes an extra click to view your groups and iCal does away with the convenient mini-calander on the left, and demands an extra click to see your calendar list. I like the new year view in iCal, but just about everything else is a step in the wrong direction when it comes to productivity. I don't have a 10" monitor at my desktop. So I would actually like to see MORE stuff in the iCal window, not less. Also, the animations in Week, Month and Year view are both distracting and a waste of time.
With Lion, Apple added some new features but REMOVED a lot of the ones that were working great. In previous releases they have not done that to this extent. I've been on OS X since Puma and have been very exited about every upgrade except Lion. I think Lion is Apple's Vista.
But the prospects of being able to stay on 10.6 looks pretty bleak because of iCloud being Lion only. I'm totally dependent on MobileMe, and when it closes next summer, I will probably be forced to move back to Lion. I sincerely hope that Apple get their act together and offer iCloud support for 10.6 users before then. After all, iCloud is available on Windows Vista for gods sake!
Sorry for ranting, I just can't believe the many stupid decisions Apple made with Lion. Thankfully we have Snow Leopard.
