Re: Your wish is granted.
Hm. My previous comment seems to have disappeared, so ...
Chromebook + Crouton is the way to go if you want to run something close to a 'full fat' Linux in tandem with ChromeOS - installation is an absolute breeze and I've now got everything I need to do development on the move should I feel the need to - xfce4 on the full-HD screen really is rather nice, and the ability to switch between xfce and 'native' ChromeOS using the top row of the keyboard is an added bonus.
Storage-wise, I trust Google about as far as I could physically spit Scotland so I've bolstered my local storage with a 16Gb SD card (interim measure, a 64Gb card is on order) which does the job nicely - especially, as the review mentions, you aren't left with half the card sticking out of the slot. Of course, if you want to go down the USB flash-drive route there's nothing to stop you. That said, I don't have zillions of Chrome apps/extensions installed (apart from uBlock, Ghostery and all the usual suspects) meaning I've got the best part of 7Gb free on the internal SSD.
FWIW, I picked up the full-HD model for £219 at a certain high-street vendor who are never knowingly undersold - they were doing a £50 off deal at the time, although I don't know whether this offer is still running. Either way, I'd have happily paid full whack on the strength of the display alone. For a 'cheap' laptop it's an absolute belter.
