I switched from a MacBook Pro to a Precision 5520, which is sort of like what a developer edition XPS 15 would be, if it existed. I have exactly one complaint about this laptop, which is the touchpad under Linux. Initially, Ubuntu used the synaptics driver, which I simply could not lower the sensitivity enough to make it bearable. I have uninstalled the synaptics driver and now it's using xinput. This is a marked improvement, but I still can't use touch-to-click or I will get too many erroneous clicks around the screen while I'm typing. Also, and somewhat more annoyingly, I can't right-click without tap-to-click. I'm not sure what to do about that at all. Overall, I think the problems are software. The keyboard is great, the screen is great, the battery life is very decent.
