buy out of palm will be great move if it leads to consolidation of mobile OSes. as of now, we have OS X, android, symbian, winmo, blackberry, webOS, etc... typically most industry have 3 big guys, that is the case for desktop too - win, mac, linux.
i think blackberry should buy out palm. blackberry makes solid devices but lack the gee-whiz factor which webOS and ex-apple employees at palm can bring. nokia in turn should buy out blackberry to create a platform which is solid, functional and cool.
