Yes, there is VectorSoft Draw. It is a native Windows CE for Pocket PC Vector illustration program. It is admittedly simple compared to desktop tools and about as powerful as Corel Draw or Illustrator 1 or 2 but it still seems a bit more powerful than anything I've seen on the iPhone or Android and it can directly edit current Illustrator and Corel Draw files. It uses MFC CE, so you will need either Redgear or to manually setup your machine to run Pocket PC MFC apps. Tutorials for this are all over this form if you search.

There is also One Cat Doodler for CE but it being unable to export/import any kind of standard format doesn't make it worth mentioning.
A few of the decent free/paid PalmOS vector illustration apps out there may run within the Styletap Palm simulator for WinCE.
You might also be able to run an older CorelDraw or Illustrator on Windows 3.0 under PocketDOS but it willl probably be slow and I'm not sure when Corel stopped supporting the 286. I still have yet to try it myself.
Thirdly, there is a port of the mini vMac 68k Macintosh emulator that may run some older versions of the Macintosh version of Illustrator but it will be in black and while. Though, it is pretty fast. I'm currently looking into porting one of the newer color versions just for this purpose.
If you don't mind booting into Linux, you can also run an older version of Inkscape within the GPE environment but it is kinda slow and isn't exactly optimized for 640x240.
(putting it mildly

Sorry if this reply is late, but hopefully this will help someone who just found this thread.
