Also palm has no progress at all:
-Palms still all run on a 16mhz processor
-Always the same tiny 160*160 screen, when they try to make it in color it's 10 times worst (I saw the new "color" one)
-No new noticeable changes in the OS (Palms OS 1 and 4 look exactly the same)
-After all those years their around they still didn't add any sound
-Only 8MB ram with no expansion (except the new palm that has a slot but no drivers for it so it's only a slot for dust to get in and damage it)

In PocketPC they upgraded a lot:
-From 70mhz CPUs to 206 and soon 500mhz
-from 4MB to 64 RAM
-Added stereo headphone jack for music listening
-Greatly improved OS (even the first OS didn't crash like PalmOS always did)
-Expansion slots to add any hardware you want from a digital video camera to a 5GB hard drive to a GPS or even a CD Writer for cheap large storage
