Cons: As others have mentioned, the power button is poorly located (near the delete key.) I'm learning, but I still hit it occasionally.
A cap-lock indicator would be a plus, but the lack thereof is not a deal killer.
The key travel is a bit shallow and unremarkable -- but I have had no problems typing on the keyboard at speed.
Here's the big hit, mentioned by others: The trackpad is awful. "Juttery" is a good word. "Randomly unresponsive" is another. The problem seems to be a combination of too-smooth trackpad with too-dry and too-smooth fingers (a trait, I assume, that will mitigate somewhat in sweaty summer weather!) Moistening fingers (and wiping them off!) usually cures the juttery response -- for awhile. But this should not be necessary. Asus needs to fix the trackpad.
Other Thoughts: According to Newegg, 48% of people end up buying this laptop after viewing it. I wanted to share a few things before you're one of them. To start off, if you like the added portability of laptops with 14" screens, you'll love the fact that, because of the thin bezels, the 15.6" display is put into a smaller package! The downfall, however, is the 45% NTSC screen. If you do photography or any media editing, you'll quickly discover that the colors displayed by this screen are beyond inaccurate. Remember The Dress, and how people couldn't tell if it was white or blue? (old Internet meme, look it up). Well, I highly suspect it won't look like either to you if you use this screen!
