I think I'm right in saying that you can play Touch on PC and that it comes free with the standard version. It won't play on smartphones though and is different from FM Handheld, which is the smartphone version. For the record Handheld isn't very good...I haven't - a few years ago I traded in my smartphone for an old style Nokia that just does phone calls and sms and I don't regret it at all. That said I am currently having to think about getting a smartphone and/or tablet anyway, as my employer is rolling out an app where all employees will be able to access work systems via a secure app on our own devices - and that definitely won't work with my phone
That said even if I do end up rejoining the modern world, I probably won't go for FM Touch - I actually quite like all of the bells and whistles that come with the full thing.
