In reply to Martin W:
Iirc the price of the Kindle fire was dropped to that of a Hudl in order to compete. I'd be put off the kindle (and was) due to the lack of access to Google play app store.
My vote is Hudl, bargain for the spec, especially if you have vouchers to trade.
PS not sure about word and excel, but my hudl does read PDFs and has a kindle app. And has a colour screen
