I've often wondered this myself. I used to have a stock incan Solitaire as my keychain light many years ago, but it was such an unreliable POS that I stopped using it. Since joining CPF I've seen so many advances in LED technology and the advent of LEDs in the Mag product line, that it seemed like a no brainier that they would update the Solitaire, but still nothing. I thought perhaps that maybe there are too many competitors in the AAA size. Certainly the folk here can easily rattle off the names of a great number of quality AAA lights, but then I realised that Mag has always been about providing decent lights for the masses, and I can't say that I've noticed many alu lights at that size for Joe and Josephine Public in shops. (At least not outside the US.) It seems like such a glaring gap in their product line, yet I can't fathom why Mag appears to have dropped the Solitaire. I would have thought it might sit pretty well with regular folk, especially if the already own another Mag.
