Thanks Matt, in the end I did go and buy an Asus EEE Pad transformer after looking at an IPad an Xoom and a Galaxy Tab. The transformer just felt right for me, I will probably get the keyboard and doc when it becomes available.
The only slight fly in the ointment at the moment is Zenio that do the digital mags haven't released the Android version of the viewer app yet but they are doing it. I find it quite entertaining that they do an Android magazine that is now viewable on your Mac, PC or IPad
Now to work out what Android apps to install so any recommendations will be appreciated.
