Not me !

I upgraded first day last time when 10.7 was released, I cant remember all the problems, but here some of the major ones.

NAS file services completely broken - was without my file server for over a month, had to buy new hardware and install a completely new *nix OS and NAS software on my new NAS machine
Apple upgraded Netatalk to a more secure version without any suitable workaround, 50% of the worlds NAS servers werent using that version, So I ended up having to work off a USB drive after 2 weeks of messing around trying to get things working

TimeMachine functionality and Time Capsule file access was affected - although i could access my Time Machines from my PC, I could no longer access my Time machine reliably from the Mac ! This was a little easier to fix, but involved reinstalling an older version of the software on both eras of Time Capsules.

Parallels no longer worked - all my Astro Win applications live on a Virtual machine plus some other stuff I use everyday that had no Apple equivalent
Needed to wait approx 3 weeks while parallels released a new version and pay for the upgrade.

My VNC services also ceased working, so i could no longer log into my Windows machine to access the files I could no longer access on the Mac ! Had to wait for a new version of my VNC software and pay for the upgrade.

I was disappointed since Apple knew most of these things well in advance and yet offered no warning.

So for me my system was completely crippled and I wasted huge amounts of time trying to identify the problems and find solutions and try many workarounds blindly - some of which worked and most of which did not - I vowed - never again would I let my guard down.

Dont get me wrong I still love my iMac but next time I will not throw caution to the wind in the belief that because its an Apple it will work !
