Hi Marggie
We've talked about tablets before. I have a Google Nexus II, which has a micro USB port. I print wirelessly to my Epson printer, but also, if you look on Youtube, you will find videos of printing from the Nexus with a Micro USB OTG cable, direct to a printer, which you can get from Amazon for as little as 99p.
You would probably need a driver or/and app from printer manufacturer.
I'm pretty sure you can also use a wireless keyboard and mouse and other things using the same cable.
The Nexus mentioned earlier from Argos is a good deal, but is the earlier model. Amazon do the Mk 2 with 16gb for £150. I've just bought one for someone else, and so far is the cheapest Mk 2 available.
Without knowing, just what you intend to use it for. The main factor may be whether a 7" tablet would serve your purpose.
I assume you're due here soon. If you haven't made a decision by the time you get here, you are more than welcome to give mine a try.
