In other posts I have said that I need 2.2 for work reasons so I have had to replace my scroll.
In the end I went for a Linx Commtiva N700.
It is very similar to the scroll (7" Android tablet 800 x 480 display) but has the following advantages:
Android 2.2
Market enabled
Smaller (180x110x12 vs 200x130x12) and bit lighter (375gm vs 400gm)
Capacitative two touch screen vs one touch resistive
GSM (unlocked)
Bluetooth
GPS
Camera front (VGA) and rear (3 Mp)
Comes with faux leather case and 4GB microSD
It doesn't have HDMI out and only one mini USB (neither a problem for me)
Despite having 2.2 it still won't run Flash (processor too slow) which is biggest downside.
Of course it costs twice as much - £299 from Staples, also saw new one on eBay for £245 - if you have a Staples card you get 10% back in vouchers, or 600 Tesco points if you buy from Tesco, also £299.
I did think about the Galaxy tab (best price I could find £399 without phone contract) but I don't like the fact it has no USB, and apart from processor is no better spec than the Linx. Also ipad is much cheaper now, £329 for 16GB wifi only model from Tesco since they announced iPad 2, but ipad is too big and way too locked down for my liking.
Not suggesting at all this is for anyone else to follow but I thought you'd like to know what else is out there.
Oh, other downside is no forum like this. There is a sub-forum on modaco but it tends to have few posts and be very technical (rom building etc) not for "ordinary" users like this forum!
Cheers
