Any plans for linux?

Any plans for linux? There is no math app in linux with convenient paper-like interface.

If you made new app called prime, why not make it crossplatform?

Thanks for free version! Do you plan make more versions? I don't need full version, 1500€ is too expensive for me. But free version functions + 'Symbolics' will be enough for me, but not for 1500€. And I also want use mathcad on ubuntu, but now I can't.
