Ok, for the sake of keeping this discussion going. . . .
I too am lured by the promise of what this product offers.
Yes I bought one (MODlive). Here is what i have learned so far.
1) Mounting in anything other than goggles is a pain. The display is very close to the main cpu unit due to the nature of ski goggles. The attached picture is my solution for mounting inside my G2. An evening with a bag of GoPro mounts, a craft knife and a tube of 5 min epoxy yielded a workable solution. There is a small issue with reduced peripheral vision on the right side, but with careful positioning and left hand patterns, its impact is negligible.
2) The metrics displayed are primarily intended for skiers and so some stuff is a real pain. Most notably altitude is ASL when what we really care about as wingsuiters/skydivers is AGL. I only have one jump on this thing and my DZ is at 462 feet ASL - that is not easy math to do in flight! Because this is an Android computer (2.3.4) the software can be written to do anything you want. If you are following Jeb's FB page, you know that he is working on an application specific to WS/SD - this should hopefully cure that issue. If it doesnt, there is a business opportunity here for someone.
3) There are still issues that i do not know the answer to. How susceptible to loosing the signal is the unit (do i have to sit in the door)? If i loose the signal, how long to get it back? How accurate is the alti and how quickly does it update? My jump yesterday was in 66 knot winds aloft and 25 knots on the deck. It was the only load of the day and after scattering people over the countryside, the DZ shutdown for the day. I do not like landing backwards and was very much in survival mode (for posterity, it was a stand up in the grass - right before being pulled over backwards!)
When i have more jumps on the thing or if any other group posts some news I will update this.
