I may be a bit wishful after seeing the demonstration of the Palm Pre but knowing that you can get Angstrom Linux on the Palm T/X, there isn’t any reason that you couldn’t get the Palm WebOS shoehorned into it. But I’m assuming that CPU power and memory will be issues. Still one can be hopeful that since the Linux Kernels are nearly the same version, the WebOS environment is the only portion that needs to be ported. It might be a bit sluggish, but the Angstrom installation has built-in over-clocking of the T/X processor so that hurtle could be overcome.
Having read this article about how to Dual Boot Linux on a Palm TX. I then downloaded the linux distribution described in the demonstration from the Reware Project And loaded it on a spare 2GB SD card as outlined. IT works as described, and it didn’t do any harm to my normal Palm OS installation. After trying the music app from this project and drilling down through the filesystem to find a complete Linux distro, I downloaded another system called Opie from here http://atrey.karlin.mff.cuni.cz/~miska/ and have now been throughly impressed with Linux running on my Palm.
The OPIE project is more or less a replacement PIM running over the Linux, and contains many Palm PIM equivalents, and although not as polished as the Palm applications, it makes for a very good beginning. From what I can know, the OPIE system boots off a Ångström Linux distribution of a Linux v2.6.23 kernel. And while the networking elements of the Palm T/X don’t appear to be operational, it’s still impressive.
