Pro's, in general it is a great system all round, I love it.
Con's, the main one for me is the fact that I can't use the Bluetooth keyboard, the Android one Sucks big time, hides up some of the things you are trying to change.
The size of the adjustment buttons, is a major drawback which the Bluetooth keyboard would fix, needed if you have large fingers, or a lady with long nails.
This is being sold as a going product, so it should take priority, over the free Mattercontrol, as far as I am concerned once you sell it in what type of form, it is no longer free. Would anybody buy the blank tablet.
If anything turns me away from this it will be this factor.
I printed a stand for my T10, but it will not be suitable for other machines, I love the T10, but have problems with large fingers and the Android Keyboard, tried using a bluetooth one but the T10 fails with it, I am hoping that they fix that problem real quick, but I don't think I will hold my breath on it.
