I hate the idea of all those icons displayed over the desktop too.  I realize it only does that when you use the Launchpad but desktops should be tidy!  It even does that ugly thing that iPhones do with folders.  Blech!

Perhaps this is mostly because they want to cash in and put the App Store on the Mac

I was using my laptop and connecting to my iMac across the network and browsing through its files. The connection would occasionally drop and it would sometimes show folder contents as empty when I knew for a fact they were not. The option to share the screen would also disappear at random and occasionally the whole iMac would disappear from Finder.

Much cursing was done.

The problem turned out to have an odd solution. I noticed it was connecting to the shares using the Windows smb protocol rather than AFP (Apple’s File Sharing Protocol) so I disabled smb on the iMac. Now everything works fine. At least until I try to access the iMac from Windows anyway….
