a totally OPEN hardware specification including the information required to program the SD card stuff.
Unfortunately, I can't influence that right away. But they are also selling their device as a "reference platform" so they might be willing to provide the spec. The question is of course if they are capable of maintaining it resp. giving support in case of trouble.
If you could convince people that it would be feasible to source patch the stock Linux Kernels to run on this device then you would have a lot of support from the Linux Handheld community.
Let's see - I can talk to them about the OS issue only if I am backed by enough interested potential buyers of the hardware...
I believe my SL-C860 is better than this offering but I would be tempted in the future by open hardware specs. - In fact the to purchase another PDA the hardware of a new system would really have to trounce my 860 (and I would have to feel the need for that power) to sway me away from waiting on an open HW Spec handheld.
Okay - it seems you are a "Power User" who has already paid about twice the $$ than this device would probably cost. It addresses a lower-tier market (like the original A300 Zaurus or what Royal was rumoured) which was up to recently filled by the SL5500.
Do it !, open hardware that can be maintained by open source developers developing drivers for later kernels etc.
Personally, I completely agree with that model (I have recently thrown in the idea of the Open Hardware Spec Foundation into the discussions) - but in this case it will (not) yet work that way.
People will upgrade to your next model as and when they need more power and you may actually start a bit of a cult following for your device.
Hm, that depends. I think the success of the Palm Zire is not necessarily the option to upgrade but the very good performance for its low price. And my idea behind such a project is to fill the low-tier demand below the SL-C and SL-6000 models from Sharp.
