I prefer StuffIt over BOMArchiveHelper.app because StuffIt shows a status bar. Who cares if it's a little slower (which StuffIt seems to be), I prefer to know how long it's going to take. What's better: knowing it'll be a minute, or sitting there with NO clue for 50 seconds?
The only downside is the ridiculous process StuffIt makes you go through to download and install even just the free expander. Not only do you have to supply an email address, you've got to check your email for the super-secret download location.
In 10.3, if you had a window open and you threw that folder away, the window closed. In 10.4, the window stayed open but would close if you emptied the trash. In 10.5, when you throw away a folder whose window is open, the window stays open and changes to show the parent directory. I think these behaviors are great, sucky, and even worse, respectively. I like being able to throw away a folder and close its window in one motion, and I like the INSTANT feedback that I threw away a folder whose window is open.
Also, if you move a folder while its window is open--say you're looking at 'Desktop/Stuff' and you drag 'Stuff' to the Documents folder--in 10.4 and earlier, the window stayed open; in 10.5, it drops you to the parent folder. (Need to test on 10.6.)
Adobe's new 'element' icons are inconsistent. 'Bridge' gets a capital B and lowercase R. Flash gets an uppercase F and lowercase L. InDesign gets an uppercase I and small-cap D, and Illustrator, strangely, gets an uppercase A (for 'Adobe') and a lowercase I (for 'Illustrator.') I guess they couldn't accept how capital I and lowercase L look next to each other, and they didn't want to go cap+small cap across the board since InDesign is the only app with a CamelCase name.
For Dreamweaver's 'Dw' and Photoshop's 'Ps,' the uppercase and lowercase forms of the second letter are indistinguishable. Those are the correct spellings--they are NOT 'PhotoShop' and 'DreamWeaver.'
Adobe Device Central and Adobe Stock Photos have typical icon-style icons, and of course Acrobat is the crazy three-sided thingie that it's always been. Acrobat is 'Adobe Acrobat 8 Professional'; all other apps use 'CS3' for their version. Acrobat has always been the "odd man out"--sticking with unique version numbers as the rest of the apps too on CS, CS2, and CS3 versions. Acrobat also gets revisend independant of the rest of the suite: CS came out and shipped with the already-existing Acrobat 6, then Acrobat 7 came out, then CS2, etc.
