I have the dock on the left of all of my Macs .
I also have an issue where if I've got multiple windows from a single app open in different virtual desktops, the only way to get to the other windows from the app is to click the dock icon - it can't be done via keyboard as far as I can tell. (And yes, it's infuriating.)
Then again my use of the dock is sporadic, mostly for accessing recent downloads.
