Sharp Ships New PDA Running Linux 2.4

Their plan is to get some apps created before marketing it to the public. Check it out" I wonder if the USB port on the docking station would let these work with the Happy Hacker keyboard ...
Two things instantly come to mind...
1) The newest VM is probably the way to go for an embedded user responsive system. Comparisons posted here on slashdot show the newest 2.4 VM to whip the 2.2 VM
2) Not totally sure about this, but wouldn't the 2.4 kernel do a better job os supporting USB devices?
There's probably more too... As long as the OS is flashable (I'd be astonished if the developer editions had the OS ROM burned in...), then 2.4 is most likely a really good decision...

Short question :
Can a Registered Developper Port something else than Linux to it ?
The PDA actually looks sexy on the hardware side, not on the software side (A friend of mine bought a Linux-iPaq from Lisa and it appears to be quite slow, lacks responsiveness and also burns its batteries in about one hour).
I think some special projects like RiscOS would be more adequate.
Trolling using another account since 2005.
The concern isn't (just) with the license, it is with the lack of compatibility and interoperability. If you run Qt/Embedded, you can't share the screen with applications written in other toolkits or in raw X11.
Does that matter? I think it does. It places the Sharp outside the family of other Linux-based PDAs and embedded systems, meaning that code for other PDAs can't easily be ported to the Sharp. It also means that workstation applications are much harder to port--even if you change the UI to accomodate a smaller screen, much of the display logic can be shared between desktop and handheld applications.
A cheap Qt/Embedded developer's license just won't help. Sharp needs to provide X11. They can still run their applications using Qt/X11 on it.
It's a developer edition - perhaps they want folk to develop apps that run comfortably in 32MB, then when they release a production version with 64MB or even 128MB multiple tasks from multiple developers should be able to run side by side without memory problems. Just my 2p worth.

What other PDAs? Really, Linux handhelds are mostly vaporware. There are not tons and tons of small-screen Linux apps to be ported to the Sharp. One of the biggest problems normal users have with X11 are all the differing toolkits. If Sharp wants to target normal users then it is going to need a consistent interface. This is an excellent time to establish a precedent for Linux PDA applications.
iPaqs have been running Linux for several years and are quite popular.

There are tons of X11 apps with X11 display logic that can be usefully ported to X11 handhelds with only small modifications to the UI.

I have never seen any evidence for that, and repeating that claim endlessly doesn't make it true. In fact, I suspect most people couldn't tell a well-written Qt application from a well-written Gtk+ application. Furthermore, even on Windows or MacOS, developers use many different toolkits, yet users don't seem to notice.
