I expect that, given enough time, developers and hackers will fill in what the gang at FG are unable to do, unless the Android world just shrugs their collective shoulders and walks away from this platform.
I don't think that will happen. Grid 10 has a good processor and has considerable potential. Another month and we are likely to see many, if not most, of the bugs resolved, Flash 10.3 and better battery utilization. Eventually someone will create a 40-pin connector to USB cable for less than $30 and an affordable HDMI output cable as well.
I will start exploring some of the bluetooth capability this week. My Grid 10 GPS couldn't find any satellites this afternoon, though my HTC Hero had no problem locking in eight or nine of them quickly. I will also drop in a 32 GB micro sdhc and see if Grid 10 can format and use this feature as well.
For an extra $100 you can go for the polish and power of an ASUS Transformer running Honeycomb, with access to the Android Market. Not every Grid 10 buyer will want to hang around and slog through the digital swamp while the kinks are worked out, and you can't blame them.
I remember all too well trying for more than a year to get my Okidata printer to work with my Osborne portable and Wordstar - never did get it right. Compared to the CP/M and Win95 days, this isn't bad at all...
