i don't know why no one has ever sucessfully produced a displayless, batteryless, keyboardless (or maybe not?) 'laptop' to replace a desktop. i'm sure a manufacturer could easily adapt their case design for little cost, they would give a huge saving in space, much better aesthetics, would be ideal for a media pc (in place of ur dvd player), much easier/cheaper to transport, enormously lower power... [the savings on air con alone in high-density environments would be huge, not to mention the NOISE]
but instead we have had over-priced, ugly shuttle bread boxes and optiplexes?
you could even have 19vDC terminals at [some] officies/labs etc so u don't even need a power brick each. (i assume it would be more efficient to deal with it all together?)
the more i think of it the more i like the idea..
and a little more on the original topic; i really like the idea of having the screen dimm as a power-save option! and i'd like to see mucch lower brightness settings for use in low-light/night conditions toooo. Think of all the pretty [er, i mean cool/futuristic looking] things apple could have done with it though; gradient fade etc, lol.
and there is NO excuse for leaving PCs on 24/7 (i am talking particularly about corp/lab environments) other than lazy/incompetent/ignorant admins; WOL works, from OFF, and S3 is much better than 'on' if not.
One downside of laptops from an SPCR POV is that very few, if any, are optimised for low-noise operation; desktops are much more flexible in that regard. Given that many SPCRers use notebook HDD's and mobile CPUs (Mobile on the Desktop), we're slowly catching up with the low power consumption leaders.
many laptops are virtually fanless (possible for normal use with undervolting.. i must admit to not following C2D on laptop much), so all u need to add is solid state storage and ur there. whilst most are above SPCR (i would say mainly due to the character of the noise, volumes tend to be low most of the time ie when fans are off) they are quieter than your typical PC. my point is u can do a lot more to reduce/remove noise on a laptop than u can to reduce power on a desktop.
