I've been reading throught he forum and I think that for right now, A6 would be the best to stick with.
A7 is so new that they haven't worked out the kinks... There seems to be quite a few WED bugs that would bother me and probably more that haven't been discovered, etc...
Another question though...
If later I chose to upgrade to A7, would I need to change anything in my code (C-Script) to be compatible? (which would be a headache...)
