If you try the recent version of Ubuntu, you will see a real nice interface and a "next generation" OS: faster startup and shutdown, less process and memory use, less power consumption. Applications are as easy to install as with Windows ; hardware is automatically detected (wifi, printers, bluetooth, ...)... amazing !
Some users also consider that such Microsoft-Apple-Google-Facebook big companies are not safe for respect and privacy; they are always searching for an alternative.
So, Why not selling a "Sticky Password" Linux version, which also could be an option for Windows users with an extra cost ?
I can now see other good products on Linux (LastPass) present on this market (but not so good as SP)...
perhaps is it a good idea taking a decision before it's too late ;+)
