Boy was I looking forward to Lion. I switched back to Macs in 2008 as I wanted nothing to do with Vista. SL was enticing. A few learning curves but in short order I perfected to my needs. In fact, so happy that I soon owned an iMac, MacMini, MBA, iPod Classic, Nano and iTouch 3 & 4 gen! I waited for Lion upgrade until Dec '11, meanwhile read earnestly, bought the Missing Manual and was super excited to gift it to myself for Christmas. I did an erase a re-format install on my iMac purchased in Oct 2008. A bit bummed initially that I couldn't open any documents so I went back to Apple store and bought Pages. Then couldn't load PSE so again went back to purchase the Lion compatible version. Oops, now I had an Apple store problem with my account VISA that I could not get corrected online. Learned that is common to others and takes a few hours for Apple to correct. My VISA worked again the next day and by then I had a whole list of software I had used that wouldn't launch in Lion. I slowed down buying stuff and started using the new OS. I gave it a fair shake- a month. I went from an excited purchaser to thinking that Lion and Vista are very similar in frustration building. Too big a jump for me. For example, Pages. I disliked Pages save-a-version. What happened to save-as? Why can't I open a NAS file and save-as to desktop under another name? Why do I have to unlock all my files to work on them? I don't do well with relearning everything. Which is what I had to do every day with my new Lion system and software. I gave it 30 days. Two days ago I had reached my exasperation limit. The Missing Manual went back into my bookcase. My install disks came out of the closet. Snow Leopard is back on my iMac in all it's glory. I no longer drool over the new Macs. Perhaps in 2-3 years I will venture out again. But for now I am cozy, comfortable and productive once again.
