:D Bluestacks is a completely legal and Android emulator for PC. I have been playing Final Fantasy Tactics on the PC for couple an hour. It works really, really well with a mouse pointer. It's still not out on Steam yet, so it alternate option to play on.
FFT has been playable on PC for a very long time through PSX/PSP emulators.
I guess it's one more option - and if the idea of using mouse controls instead of keyboard appeals to you, an interesting one - but considering that this is a site dedicated to modding FFT and the mobile versions are the least mod-friendly I dunno if you'll see a lot of interest for it here.
