Boot up and Shutdown times are equally irrelevant. I shut the PCs down on weekends. Am I going to notice or care that it takes a few more seconds for a machine to boot up or shut down.
At times I am astounded how hard it seems to be to add a disclaimer such as "In my opinion" or "I think" to statements like these.
In my opinion, using Linux-based OS:es mainly on an EeePC, which drains the batteries pretty quickly in sleep and is used daily in school, where I might need to haul it out of the bag and use it quickly, OS boot time is very important. (I also happen to have a stationary computer with a glitchy powersupply that turns power right on again after a soft stop, such as after a hibernate. Quick bootups are nice there too).
Oh and thanks for helping out the environment by keeping your PC turned on all week.
I really don't give a shit about weight. All I want is a browser, a real, full-sized keyboard, (none of that function nonsense) and a reasonably sized display. Also a bash shell, but that goes without saying. I want this for around $200, and I want it to last me at least 3 years. I don't need power, I don't need it to be lightweight, I don't even need it to work for more than an hour without a cord. These things are nice, but I'm just looking for something that's reliable, ergonomic, and cheap.
Ok! Now I know what to get you for christmas.
