Here's my 2 cents....my money needs to be spent soon.... apex or cerebra
IF you really need a controller right away I'm sure you would be very happy with the Apex and what they have to offer. If its just a matter of money burning a hole in your pocket than I would recommend holding out for the Vertex. I think the android platform will allow for you to do things never dreamed of by current controllers.
The wait is killing me too, but I plan on sticking it out. With a little luck we'll be able to pre-order soon.
