circmand.... you negative Nancy! 
I really like where this tech is going. It's just not getting there fast enough. Seems to have been in a rut for some years now.
Would be cool having a full-time DD. I might hit the pub every evening and shave on my way into work every morning. 
And I do like how it is a good supportive role for disabled people who need to get out and about.
Sadly, nothing is ever cost effective and I can only imagine the $$ on this type of system when it is "A Go".
Still, awesome.
