I could be nitpicking since its still a nice keyboard. However, for that price, you should expect perfection.
The fans are loud, but only if you use a significant amount of CPU, which I almost never do. If some errant process cough flash cough is taking up too much, I can hear it and deal with it (this alleviates the annoyance a bit).
The trackpad, on the other hand, is brilliant. Using multiple fingers works every time (on Linux, anyhow) and it's actually pleasant to use. I think that all your issues with it would be resolved with Linux; the bloatware is also gone. I've played around with Mac trackpads, and like this one more.
Have you had problems with the space bar? I have to press it harder than normal to get it to register.
EDIT: I've been meaning to install linux on it, now I have a real good reason to try it out. What distro are you using?
I have not had any issues with the space bar--my only problem has been with the left shift key.
I have to add that the only gestures I've actually used are multiple finger scrolling, pressing with multiple fingers and circular scrolling (which is pretty cool). I don't have zooming--it tends to annoy me more often than not, so I don't know if that works well (or at all) on Linux.
The specs are amazing for this 2.5 lb laptop, but it still doesn't do justice to how disappointed I am with the keyboard. The travel distance is so minuscule, its uncomfortable to type on. You find yourself slapping keys but feeling like you didn't really press the key. The space bar sucks, you have to hit it pretty hard to make it register.
The trackpad is pretty small and awful, 2-finger gestures only works 50% of the time. I had to disable the fingerprint reader because it would activate everytime using the touchpad (you would always hit it by mistake).
Those are literally the only 2 things I dislike about this laptop, the keyboard and touchpad. I use a portable bluetooth mouse a lot (Razer Orochi) which does alleviate a lot of the touch pad issues, but the keyboard is god awful.
That said, the power media dock is a novel feature, external graphics, blu ray and all...I haven't used it once haha. I think that's because I have a nice custom built desktop, no reason to use the PMD.
EDIT: The keyboard is worse in my opinion in comparison to a macbook air which I owned for a year before I sold it.
I just wanted to add on top that, I tested out a Lenovo T420 edge...quite possibly one of the nicest keyboards I've ever typed on.
