Devo ammettere di essere molto soddisfatto di SMath Studio, uno (a mio giudizio) dei migliori software freeware matematico disponibile al momento per più piattaforme (Windows, Linux, Windows Mobile), che viene aggiornato con una certa regolarità dal suo creatore.
In questi giorni il programma è giunto alla versione 0.80 e porta con se finalmente una versione Portable del programma da poter mettere nella propria chiavetta USB… come dire la piena maturità (versione 1.0) si avvicina sempre più.
