I have an iPad, an Asus Transformer, a Hannspad, an Advent Vega, a 7inch witstech and a archos.
I have to say that by far the Archos is the best value for money
The iPad may be slicker, but mainly that is due to the software
The transformer more polished
but the Archos is still better value
There is a slight rippling on the screen, when you push hard from behind, although I have heard that this has been fixed.
I have ordered but not yet tried the 3G integral stick, which is genius!
I love that you can charge it via USB
It also has a great screen and good battery life, not as much as the 10 inchers, but close enough, a good 7 hours.
my only gripe to not give it 5 stars is that one of the few areas where it is let down is the lack of encryption - it is an omission from the standard honeycomb....possibly as the unit does get a little hot with continuos use, not too hot to handle, but you notice. I guess that the lack of a decent heat sink, might cause it issues with the hour that it takes to encrypt a tablet....
I now also (because of work) have an Ainol novo 7 elf - they are now the best value tablet on the web, but I have not got a 3g dongle to work yet....
