I was one of the original mbient kickstarter sponsors. I got the kit, but was just daunted by the IOS developer registration.I don't have a mac so I thought that I could not implement the IOS version anyway. The android SDK tutorial sounds just too difficult. So I think the concept was great but not simple enough for me to actually use. The mbient stuff has been sitting in a box since I got it. I think the idea is great and idiot that I am - I actually became a backer of the 2.0 version today. I fear that that my contribution is more of a charity since it is extremely unlikely that I will use the 2.0 version either.
I am pretty good with arduino's and PICs but somehow the mbient system just seems too confusing. It's like the raspberry pi - of which I have several - but they also all live in the scrap box. The linux system is just to complex - too many libraries to download - too many commands that make no sense - just do it by rote - endless crashes and unreliable operation. I'll say one thing - the arduino is simple and the IDE fairly solid. I use teensyduino extensively for a commercial product and it is rock solid.
I am not sure why I am writing this rant. I am not looking for a solution. I wish you guys at mbient luck and maybe my backing helps you out in what should be a great product.
