What to expect, what to watch out for, does upgrading make sense at this iteration, is it going to be a disappointing hassle or a marvelous new world?
I'm on a late 2009 iMac i7 2.8GHz, 8GB RAM. My operating system of choice is Snow Leopard 10.6.8. What I use it for (other than wasting time on the internet), is word processing, a bit of Lightroom processing, as a media center to stream music from and watch movies/TV on, FCPX, and miscellaneous minor stuff (f.ex. displaying 77 million paintings
Snow Leopard does everything I need it for. As an OS, 10.6.8 has been extremely stable for me, very efficient, with minimum of bugs and the bugs that bug I have reliable work-arounds for.
Meanwhile, there's been nothing in Lion or Mountain Lion - on paper - that enticed me. The very idea of "the cloud" enervates me. In general, I tend to be a very slow adopter - I waited for Tiger before I got off OS 9, and then stuck with Tiger until I bought my late 2009 iMac in early 2010 with SL installed on it. I've been stuck on it ever since.
I use my computer as a tool, and I'm not particularly interested in fiddling with programming or excessive maintenance. I like the OS to get out of the way and simply let me work with minimum of fuss.
So, I'm happy with SL. However. More and more apps no longer support or run on SL, and some of them I need (new Dragon Naturally Speaking). Others which are super important to my work, I fear any day now are going to drop SL, and I cannot afford that - example FCPX (still supports SL, though I fear just barely, what with optimizing for the MacPro and Mavericks). I therefore think the time may be approaching when I have to make another OS move - I've managed to sit out Lion and Mountain Lion, but don't know how much longer I can hold out.
I know I'll lose some legacy apps (f.ex. 77 million paintings needs Rosetta), but I'm more interested in other things, hence my questions. Assume that I've read Apple's Mavericks page and Siracusa's review, and glanced at the commentary on the zoo of early Mavericks adoption on Macrumors.
My questions for anyone who can compare 10.6.8 to 10.9 - because I have ZERO experience with Lion and Mountain Lion:
1)SL is very fast and efficient for me most of the time. Is 10.9 going to be a rainbow beachball spinning lagfest in comparison? I know people say 10.9 is fast compared to 10.8 or 10.7, but I'm interested in 10.6.8 ---> 10.9.
2)Are many apps broken or doing worse running under 10.9?
3)Is the transition from 10.6.8 going to be frustrating? Here's what I mean - I find some "upgrades" really downgrades in UI - as an example the time-wasting graphics behavior of opening/closing apps etc. in ios 7 compared to ios 6. Eyecandy is fine, until it interferes with getting work done.
4)Any gotchas I should watch out for?
5)Do you find 10.9 a "must have" or at least a worthy upgrade from 10.6.8
6)Is the water OK? Can I jump in now? I'd still like to probably wait until .3 or .1 at least, but how's it hanging so far?
