I rate the G11 as I would a current Honda, very well engineered, not the making up its short comings with fancy gadgetry.
You can still tweak it, the Ovision OPW is a case in point.
The G2 is its weak link at the moment. I think from reports it is still 6 months from being ready.
If you can get a G1
I have no issues with mine. Yes, it is like going back to an abacus, but it just works.
