It is safe to say that any stability problems one might face with synfig or other open-source software are WAY WAY out weighed by access to this forum with the developers here to help. It is also nerdier and gives you e-cred to use open software.
*note: stability seems to be a LOT better with linux than the windows version I used to use.
Oh… and play Open Transport Tycoon Deluxe! OTTD.org!
Good to hear. It got super crashy for me and I waited until I switched to linux to give it another go. Runs like a dream! I guess I should have gotten a newer version in the meantime.
