Who really cares about boot time? Or time taken to open an app, for that matter.
My early 2009 Mini with the original 120 GB HDD 5 GB RAM and Mountain Lion installed, is usually on 24/7. The apps I use frequently are usually open. It takes a moment to wake from sleep, and main apps I use are adequately fast to work with.
Yes, it did take a minute or so to boot this morning when I took it to work and used it with an LCD projector, but during that time I was preparing other things.
Yes, it did take a minute or so to boot after the minute or so it took to set up again when I got back home, but I had other things to do then too.
I have other things to do besides waiting around to see how long a computer takes to boot, no matter how long it takes.
