By the time TT3 comes out, there will be new Clie. The fact that TT2 has just debuted recently, there will be probably 6 months until TT3 actually comes out. Would you compare a PDA with something from half year ago?
neither. I like my Tungsten C and NX70 just fine. Beautiful screens, work excellently.
I can't see any other PDA's for me. I have two great devices that will keep doing a great job and not be obsolete any time soon. The T|C is my favorite and has great memory.
