Baronic, I'm deciding between two PDA.
I'm not sure which one to pick.

I'm looking at HTC TyTN II & HP iPAQ 612C.
My budget only fits these two. [2nd hand offcourse]

I'm not sure what I want in a PDA, maybe you can just give a simple conclusion in which one has the biggest positive points.

PS: Do any of these 2 PDA has the capability of changing [by seem editing] the LCD resolution from 320x240 to 640x480? Would there be huge lag?
