I upgraded last night. Chose to do an archive and install rather than a clean wipe (which is still an option, although Apple has hidden it away a bit), because I only have *one* backup of my data, not the *two* I would feel confident about doing a clean wipe with. Shrug, call me paranoid.
The two things that aren't working for me at all right now are Menu Meters (a program that shows real time data about my computer, I use it to see how fast I am uploading or downloading at any given time), and EyeTV 3. Apple has conveniently provided a little dialog box that tells me when a program is incompatible with snow leopard and what version it is (presumably so I can check for an update). My printer driver also needs to be updated and OSX now does this through Software Update to download these rather than installing them off the install disk like they used to. The developer for menu meters says he will have a new version out soon and presumably Elgato, which develops eyetv will too.
My CS3 apps all open nice and quickly and seem to be working properly, although I haven't done any major testing.
Other differences I notice that will change my workflow just in general:
- Holding down on an open application's icon in the dock no longer provides an option to force quit it (you must use the keystroke option+apple+esc or choose it from the apple menu), but instead a cool new expose feature replaces it, allowing you to see all the open windows in a particular app (all 9 windows of firefox anyone?), INCLUDING the ones in the dock. This will be super handy for use in Mail.app with my habit of minimizing dozens of emails.
- My apps seem to load faster than they used to. In particular, Safari loads up in less than a second.
- The new spring-loaded folders in the dock are going to be really useful for dragging and dropping things.
