You are wrong when it comes on brightness on batteries. Either you had it set to less then maximum in power options or your ambient sensor was messing up with you. this laptop can produce maximum specified brightness even on batteries. Also, when comparing it with Asus, you were wrong again - this one has higher maximum brightness.
I recently purchased this Ultrabook, less than a week ago. I'm unfortunately experiencing a serious problem with it, i.e., on battery power, it is randomly shutting off (incredibly annoying), ..waiting on Acer's Tech team to get back to me on this. Also, all Skype calls drop (still trying to figure this one out). The keyboard also takes some getting use to. If it wasn't for the random power shutdowns, I'd be happy with this computer. Hopefully Acer gets back to me, ...or I'll be at the Microsoft store from where I purchased it, to return it (not worth the money, if this is what I have to deal with).
As usual, there's at least one no added-value comment by an Apple fanboy (sort of Taliban). If tomorrow Apple were releasing a piece of hardware with a spoon (incredibly useful...), there would always be a moron to consider it as a must-have which just makes the competition irrelevant. Otherwise a very good review.
Very nice system from Acer, about the nicest I've seen from this vendor. There are certainly more "dream notebooks" in the $1500-2000 price range these days, but hopefully some of those great features end up in sub-$1000 notebooks too, so that I can afford one (especially the better displays!).
12 millimeter bullet. How many notebooks can fit in twelve millimeter height? With its high-end ultrabook, Acer presents this question. SSD-Raid, Intel Core-i7 ULV CPU, IPS Full HD touch screen and unibody style - any other questions?
