So, [Erwin][] posted his _first impressions_ list, which reminded me that I’ve done one of my own from time to time, so here goes.
I didn’t do a regular upgrade, and even then I don’t really remember how long it took last time,[^1] so I have no idea if it installed any faster. DiskWarrior seemed to be getting lost scanning my hard drive, so I did the _format, install, restore_ dance. The installer’s install/restore mode didn’t seem to be working either, did those two separately.[^2] My free-space story seems much like Erwin’s, with an additional uncertainty point thrown in for good measure — Migration Assistant copied over my old /Developer directory (with a new name), so I had two copies of the developer tools installed for a while.
All that being said, here are a few things that I’ve noticed:
#### Pros
- [Mail][] seems a lot faster.
- All of my [Dashboard][] widgets survived.
- Mercifully, iPhone developers no longer have to download the entire
developer tools package every time they want a new iPhone OS SDK.[^3]
#### Cons
- None of my Menu Extras survived.
- Imagine, for a moment, that you had put Script Editor in its own
Library (Window Menu → Library) under Leopard or other cats prior.
You might have thought that you would now have an [AppleScript Editor][]
reference in there. You’d have been wrong. Instead, you’d now
have a grayed-out, iconless reference to Script Editor.
- My nearby PC is still just as confused when I use “`” inside the window
switcher[^4] as it was before I upgraded my Mac to Snow Leopard.
[^1]: I frequently start the OS install and then go do something else
while it cooks.
[^2]: Possibly due to impatience more than anything else.
[^3]: Admittedly, this is mentioned other prominent places, but it’s
worth repeating.
[^4]: Alt-Tab, and if you’re running Vista or newer, Windows-Tab as well.
