I dont have to justify Lion to you or anyone, and I am not telling you to upgrade or stay on Lion. I don't sell apple products, I am just another user. I chose to upgrade my mac to the new current OS X. I have not done the macbookpro yet cause that would be just stupid to do both systems until I had Lion on the mac and had time to check it out.
What have I found
- I had one horrible performance problem with Mail and AddressBook that was caused by my previous testing of FaceTime bet on Snow Leopard. I fixed it and Lion roared.
- Lots of new features in lots of core apps and so far I like them.
- Some apps, to me, look the same, but they seem to run better and are more responsive.
- Mail, iCal and AddressBook are new and different and so far I like them.
- Especially Mails new display format.
- the gestures with my magic trackpad are fantastic. I worry about this on the older macbookpro
- I have no problems with my mac and Lion
- I have noticeable improvements in performance.
- Network performance seems better. Large downloads run at a higher rate, close to my internet bandwidth. This could be a coincidence, as its only been a week.
I will now proceed to install Lion on the macbook.
I am not seeing any of the problems you are, or I do not percieve them as problems. No issues with iTunes. No delays on the Dock.
Getting delays on the Dock, that to me would indicate a problem. If you have modified your Leopard or Snow Leopard systems in the past and before installing Lion, I would recommend a clean install of Lion. Since you have 3 systems all with problems, it would inicate to me you have done something to all three systems to cause your problems. Whay I would do is try a clean install on one and see if that works. Or you can wait for a future update to Lion that may have included fixes that fix your problems because it could be a Lion causing problems on all three systems.
I have not seen any network problems in my lan. My Airport Extreme router is at the current firmware and I always keep it at the current firmware. I never like to see network problems. How are the pings to www.apple.com? How is your internet speed test in Lion? I use www.speedtest.net and one thing I noticed between Snow Leopard and Lion. With Snow leopard my speed test was always good hitting the max of 14Mbps but during the test the speed would fluctuate. With Lion it is at 14Mbps during the whole test. Have you checked your Lion connections to you lan, network definitions, and router connection to the modem?
Have you check the console logs for errors or indications of performance problems?
I do agree with your last statement, you should stay with Snow Leopard.
