Sorry to feed the trolls, but this won't sell to those who would otherwise buy iPads (and vice versa).
This is a £250 tablet, with a £50 upgrade to 3g if you want it. The equivalent iPad is £499 (plus the cost of adding things like adaptors for reading SD cards).
I got the Archos 80 G9 (saving another £50 compared with the 10" model). I compared it with a friends iPad2 last week, and I could certainly do more of what I want to do with the Archos than I would be able to do with the iPad, unless I was prepare to shell out more money for software and pay for (and carry around) a bag of wires and adaptors.
So for me, I spent £280 all in against what I estimate would have been around £600 for an iPad2 and the required bits. Out in the real world, that difference will feed my family for 2-3 weeks.
We don't choose between an Apple product and another one. The Apple product is not something that we consider, in the same way that I wouldn't bother to test drive a BMW M5 if I want to replace my Ford Galaxy.
This isn't flame bait - if you are wealthy, have limited commitments and can live with the restrictions, you go ahead and buy the Apple device. But when I read a review of a £200-300 tablet, I don't care how it compares with an iPad at twice the price - it is irrelevant - I just need to know how it compares to other similarly priced tablets.
To answer an earlier comment, I personally wouldn't choose a secondhand iPad, given the number of friends who have had to throw 1-2 year old iThings away following battery problems. If you have had better luck, then I hope it continues.
