Oh boy I wish I could say the same. Admittedly I don't shut down on a daily basis but this didn't used to be a problem in SL. FWIW I've an old tank of a tower that has a video card on its last leg.. shutting down invariably leads to ~30 minutes of downtime while the card heats up and reconnects whatever needs reconnecting for both monitors to work.
Since Lion, I've noticed frequent hangs and beach-balls when doing even menial tasks. Transmit, terminal, texmate, a few tabs in chrome. If time machine starts backing up I can forget about a smooth Preview open or switching to a largish open textmate file without beach-ball'ing. If I want to use a Win7 Parallels VM--I can't do anything else. Even now as I type this I have a ubuntu vm running at the login screent and it causes the machine to shake off the cobwebs between almost everything.
It's certainly not a bad machine--there's 8gb ram, and tons of diskspace--good processor. In fact, I would go multiple months without a reboot and heavy use when on SL without hardly any problems at all.
Then there is the new i5 MBPro. Cool trick you can do: hook up an external monitor via thunderbolt and watch as the [left side] dock becomes a mangled mess with icons miss-positioned and wrongly triggering apps--it's like playing a game of whack-a-mole trying to open terminal to kill -KILL dock :)
The i5 has also been less than stellar compared to the older MBPro I sold to buy it in terms of performance.
Though I did improve matters drastically by telling mds not to index my (Linux) MP3 server and my Time Machine drive. That made it go from nearly unusable to just frequently annoying.
The other crazy thing I've been seeing is it routinely takes Chrome minutes to shutdown -- in fact, pretty much every time I try to reboot my MBP without shutting down Chrome first, the shutdown process times out trying to exit Chrome.
I too have experienced the Chrome issue enough that I don't even try to close it normally anymore. Force quit is the only way I exit Chrome. Thankfully, the restore tabs functionality works well.
That would be the job of the memory manager to decide when to do that. Memory could be kept in the non-free state for longer that it actually is needed, but still be marked internally to be available when needed.
OTOH, if you have paging, as you say, then something is wrong, true.
But I don't think that the screenshot shows something wrong.
