Not to detract, but are you booting on a hard disk or SSD.. the HTPC in my livingroom does a full reboot in about 12 seconds (ubuntu 15.04) and my desktop isn't much slower. Both of which are way faster than my 1+1 android phone.

I also prefer a mechanical keyboard, have my own at work as well... I hate when I'm on my rmbp, which is about as good as a laptop keyboard/touchpad interface gets...
