Rick,
Lack of Windows support may not hurt Imagine PC sales (I'll still buy it) but
it can only increase sales if you had a Windows version.
I think, even though you are not intrucing it for Windows originally that
Impulse reconsider Windows for future releases. AutoCad just released their
new release under Windows, and it displays even faster performance than their
DOS version. Granted, Windows programming is difficult and requires more time
— but I think the advantages are worth while.
