Re: No battery life listed?
The "Ultrabook" as defined by Intel, must have a battery life of at least 5 hours for the previous 2 platforms (Huron River and Chief River). The next platform (due mid-2013), Shark Bay, must have at least 9 hours.
There is absolutely no way in hell that *any* ultrabook will only last a short commute, unless you consider transatlantic your commute. Hell, I could play GTA IV on my 40 minute commute with it and still have enough juice left over to run word for an hour when I get to work.
My Ultrabook is quoted at 8 hours, and real-life use is around 5.5 hours (films/internet/music/photo editing)
Gaming will drain it in around an hour (my knees won't last that long with the heat the Kepler GPU pumps out).
RE:screen res, 1366x768 might be low for todays panels, but in the real world, I've yet to really think "you know what, Skyrim would look better at 1080p on low settings rather than 1366x768 on high." I thought I'd regret it when buying it, but actually, I've barely noticed. Note - this is not an excuse for laptop makers to stop improving screen res, but by all means let apple fanbois subsidise 2K panels for the rest of us for a while - I'm happy for them to pay the early adopters tax rather than me.
