I bought Wits A81E recently in the UK for my sister. I had a quick play around with it and its a quick device, good for browsing.

Ebook reading and videos were good, the speakers were ok - nothing special but it did the job, the gps found satellites but i didnt have a satnav app installed so i cant comment on that.
