With an external bluetooth keyboard, this solution is surprisingly good. This is what I use for light remote work when I go on leisure travel and don't want to bring my laptop.
even text scrolling by touch works for me. hackers keyboard on android is a godsent. also you can install it without the play store by downloading the apk directly from f-droid. works on a fire hd like a charm. combine that with floatingapps.net and you even can use it in an x-windows style.
