After a hasty start Lion was installed and USB Repair disks created. All went quite smoothly. I would have preferred to wait until 10.7.1 but others jumped the gun, ran with 10.7.0 and support was expected.
The installation is a HUGE download and took some time to come down, over slow Australian ADSL bandwidth. But it did come down and following advice I was able to retrieve the download and reserve it so that, in the event of mishap, I wouldn't have to download it again. Luckily it all went smoothly on the two machines I installed.
What I like
Despite other opinions I do like the three-swipe left/right application switcher, and works well with the command-tab I so often use otherwise. Thankfully they aren't mutually-exclusive.
Swiping
The two-finger swipe scrolling is interesting but takes a little getting used-to, and we will. As do all the other gestures. Get over it.
Full Screen view
I think the Dock should be available when in full screen mode. Too many apps are just stretched to accommodate the feature and don't really use the feature properly. Time will tell. Bring back the Dock!
New Mail
It was a little bewildering at first and I would like the ability to discharge the preview pane - don't think it's possible. Now I have gotten used to it, I won't be using "Classic" Mail or setting those settings - this one is here to stay.
Mission Control
Last time I looked there were multiple versions of Mail (don't know why) and while it's cute and iOS-like, isn't that what the Dock's for? Maybe it's to Wow the switchers coming via iPhone...
Rosetta
Time marches on and Adobe accounts must be wringing their cash registers with glee! All those beautiful updates now required once and for all. Hopefully we'll get faster leaner software out of the process.
I have noticed that generally speed is improved, even on my stately 3 year old iMac. Thank goodness for 8gb RAM!!
More later
