What do you mean when you say OS X is being dumbed down?
Certainly there's nothing removed in Lion which was in Snow Leopard, except Expose's current version.
Actually, I can think of two things in SL not included in Lion...
Front Row
No Colour Finder sidebar Icons (which drives me nuts)
Launchpad is just a total waste of time in OSX too.
There is simply too many apps on a Mac for them to be organised effectively via Launchpad.
Its even worse if you have Windows Emulation like Parallels, as Launchpad displays all the PC apps too!
Despite Launchpad displaying 40 apps on screen at once on my Mac, it still needs 9 pages to display them - that's an awful lot of trackpad swiping.
It would take an age to organise these into sub folders etc, so it completely pointless and a total gimmick in my opinion.
Works great for my iPhone with 40 or 50 apps, but take that to 400 or so and the existing navigation in OSX beats launchpad hands down and is much quicker and easier to use.
The things most improved in Lion are trackpad gestures, Apple apps like Mail are better and also the ability to go full screen is really nice too, but it's hardly a revolutionary OS.
The iCloud thing might be good too, but they could have easily been added this and the other features to the existing SL OSX if they'd have wanted to.
IOS doesn't translate into a useable Mac OS. Elements of it do, but not as many as you might think and it'll be a long time before IOS & Mac OSX are one of the same if Lion is anything to go by.
