All the free remote desktop things seem to suck, though. The VNC-based ones, at least, are completely awful if you're used to remote desktop.
(Of course, I'm talking about connecting in to the machine, not out of it. Every version of Windows has the Remote Desktop client; only Pro and above have the server.)
I also find myself missing Previous Versions (shadow copy) every so often, and it's frustrating not being able to use all of the control panels and MMC snap-ins.
(Example: I created an account for a visiting friend on my Vista Home laptop. After she left I didn't want to delete the account/profile in case it had files or she came back a few days later; so I wanted to disable the account. Can't do that with Home, though. The proper Users control panel is blocked from running against Home machines and the cut-down Users control panel doesn't let you disable accounts.)
Another example: Proper file sharing. (And proper file permissioning, maybe? I forget.)
One good difference is that Win7 gives the disk-image backup tool to all versions, as I remember. I missed having that on my Vista Home laptop.
In fact, after all the little frustrations of Vista Home, I'm not sure why I ordered Windows 7 Home for my laptop. May upgrade it...
