As a recent convert to Mac OS, I wonder whether there is any discernable pattern in terms of the length of time using Macs and enjoyment of Lion? Do those using Mac OS for longer find Lion less of an upgrade than those like me? I suspect they do - I know some think Lion has been designed for people like me who have converted to Mac after using an iPhone.
I converted to Mac a few years ago just as Leopard was up to 10.5.4 or so, and I loved it to bits. I'll never forget just how impressed I was by an OS for the first time ever, and what a pleasure it was to use.
Snow Leopard came out, and 10.6.0 just felt
wrong in so many little ways. I didn't like it at all for a few days. I chuckled at its "Slow Leopard" tag, but very quickly ended up loving it just as much as Leopard, or more.
Probably as early as 10.6.2 (I think) Snow Leopard was the slickest, snappiest, most user-friendly and rewarding OS
evah... I got back to evangelising about OS X at work after going a bit quiet
So my pattern has been to dislike the new OS that displaces the old beloved OS, to feel uneasy and homesick for the old OS, but to settle in over a few weeks and end up loving the new OS.
As for the crack about Lion being too iOS-y, I don't accept that. After a few Terminal tweaks and installing my various little tools, I hardly know it isn't Snow Leopard. See that as a plus or minus as you will.
FYI, my activities on my Mac: I write quite a bit, I do some half-arsed amateur programming, I do a little bit of photo editing, and I do a decent amount of gaming.
The most inconvenienced I've been is finding that Versions rapidly fills up the space in the tiny encrypted .dmg files that I sync between machines, requiring me to move everything to bigger .dmg files. That was pretty irritating.
On the gaming front I discovered that Civilization III was one of the victims of the PowerPC cull. I had to hand-edit the starting script for Dwarf Fortress 2010 to get it working on Lion. Otherwise, the Versions issue excepted, Lion is a pussycat for me.
After all that positivity, I don't like the way VLC expands to full screen when double-clicked. As choppy and ugly as I've ever seen on Mac OS X.
