There is already a C3000 ROM (beta factoring in the 4GB space used a flash), and hence that cant be used for the C1000. There is a similar ROM in the works for C1000 (factoring out the 4GB built in HDD).
So the C1000 ROM in theory should be usable on the C3100 easily.
The C3100 was a real dissapointment - notwithstanding TriSoft's raising the expectation with his "nice surprise" countdown.
It doesnt have any - absolutely ANY REAL technological improvement over the C1000/3000. How depressing can his be.
I guess the Sharp engineers and designers are taking a much needed break while the marketing droids are pushing these incremental upgrades with some "hot" Japanese language learning software over and over again to the market.
We are not impressed.
Well again, I guess if Sharp can keep making money without any real re-designs and technology features on the existing Zaurus - then why will they not try to maximise their profits while the goings are good.
But hey, the others are catching up to Sharp's act fast - 4 GB internal HDD on a handheld (LifeDrive), Clamshell design (many), built-in keyboard (the uni.com thingie), VGA screens (Nokia), nice looks (Nokia & others), QT or other open architechture (Archos/Nokia) on top of Linux on the devices to make them open (soon Palm too) - , and if Sharp keeps doling out these same features with a give here, take there attitude, they are gonna lose it pretty fast.
