Come on all you "pro-user" guys and gals... calm down your egotistical me-first attitudes towards your wants and wishes for Lion, and think for a minute.
There is absolutely NO reason why an iOS-user type interface OPTION, and iOS-friendly styled and synced App Store can't be an OPTION on the Mac. OPTION being the key word there (really?)

Considering the posted SW requirements, I personally will give Apple the benefit of the doubt that they
- a) know what they're doing and what they're pushing towards; and
- b) don't even WANT pro apps, utilities, suites etc. to even think about getting on the App Store, or start developing for it, only to be rejected. We've seen that movie recently about spurned developers, bloggers, etc. No re-run or sequel necessary, thank you.
I believe the App store is going to be for all of the "add-ons" for iOS device Apps, and for easy and friendly consumer computing Apps for your Mom.
+1 props go to the poster who mentioned this previously.
What's the average person going to do with a drive utility anyway, other than accidentally erase their drive.
Will Apple forget the "pros" and devs that make those iOS Apps with "pro-category" software/suites...on a Mac... and push them to go to Windows?... stay out of date with an old version of MacOS?.... boot Ubuntu?
I just don't think so. Even if I do love a good tech-conspiracy once in awhile.
And may I add: we pro users here should never forget that, without the casual Apple consumers, users, and buyers of iOS devices, starting with the iPod and the iTunes Store... we would definitely NOT be having this discussion, now would we? Leave the communal panic-attack to Lemmings United.
Summary: yer gettin' yer jockstraps and panties... or both

... in a bunch over nothin'.
Patience. Wait and see... because surely they'll be twisted deep enough if I'm wrong!
