I too have perfected driving without my hands, that was long ago though ... LoL ... but I will say sometimes it is awkward trying to do the one hand thing on the ppc, the wide keyboard makes it difficult, but when you're 6'4" the long fingers give me that extra ability!!
but yah that is something I wish they would develop is a speech to text system for the handheld, maybe a mobile version of Dragon? I mean hell my $200 A900 has it, why can't my $400 ppc have it?
