Running vim on a Nexus 7 is a dream; the only hassle is pairing the bluetooth keyboard (another thing to carry with AAA batteries) and a OTG cable dongle if you transfer files to usb flash.
It all depends what you want to do with the device.
One thing i like about tablets though is they are quick data capture devices: secondary camera, Swype like virtual keyboard faster that typing and paint/sketching.
Imagine trying to swivel a Chromebook's stanky front facing VGA cam to take a picture if your camera lost power.
But...
My Samsung charger is a brick. Not sure about Asus. Battery life on ARM is 4-5 hrs, Intel better at 5-7hrs, but still no match against the tablets.
For portability, you may be better off with a smaller tablet: Nexus 7 or iPad mini plus keyboard.
I would give the edge to Android for easy access to the filesystem unless you jailbreak iOS.
My Nexus 7 also runs vim with plugins: https://github.com/momodalo/vimtouch_fullruntime, Firefox and BitTorrent Sync same as the chromebook.

It sends/receives files with NFC, bluetooth, BTSync and USB flash drives via Nexus Media Importer http://nexususb.blogspot.com/2012/08/welcome.html
My iPad can't do that.

If you're travelling that may be a consideration.
