The Treo 700wx doesn't have the GPS chip in it anyway so 6.1 wouldn't really help you so much. At least 6.0 gives you the html emails and a few additionals over WinMo 5. 6.1's only real advantage over 6.0 is that it gives the drivers for GPS on such phones as the Mogul/Titan which were rushed out for public consumption before they had the software to run them at full tilt.
I doubt you'd notice too many differences from 6 to 6.1, though I assume Palm would tweek it to run a little nicer, if they were to make an official release. Now that the Pre is their main focus, I wouldn't hold your breath for another update.
