- Given what I know, I suspect our core technology is indeed better than
- Insignia's. However, to be fair, it is much easier to do our CPU
- emulation (emulate a 68LC040 on a 386 and above) then it is to do
- theirs ('486 *with MMU functionality* on a PPC). On the other hand, I
- our OS rewrite is technically more challenging than the glue that
- they've written to interface to the Microsoft code that they've
- licensed.
-
- Bottom line, I agree with you; our PPC emulation will crank, but the
- comparison to Insignia is a tricky one due to all the different
- variables.
