Acer Iconia B1

So I've wanted to get a 7 inch tablet for a while to compliment my iPad. My iPad is a great tablet but I want something a bit more portable as I travel a lot and also because using a smaller tablet is just more comfortable in certain situations.

Now the usual suspect is the Nexus 7 and that's a great tablet but I came across the Acer Iconia B1 which is about £50 cheaper than the N7 and too runs stock JB albeit 4.1, but that's fine by me.

So, what I actually want to know is if anyone here owns one and can tell if it performs well or whether to steer well clear ?
