Well WP7 is LTR based where there are so many others that are SNL based so I don't see why you'd want that.
Also with iP4 not being compatible with XHT or even PBZ, there are not much advantages over getting a FJX. Well that is of course unless you are willing to pay the extra bucks to get the pro version, but it's not out yet and there is no release date so I'd
wait a bit before jumping on that.
My friend also got a WM6.5, and WMP9 (or 10 depending on your config) comes for free, so it's a quite welcome enhancement for now although clearly not enough.
By the way iP5 will be there before christmas due to the many issues they had with iP4.
Now if you'll excuse I have to go back to my SSW cause my grandma is taking an FPB, so I can't use my UTL until she gets there on sunday. Otherwise, I'd be out trying the new YYZLJITBSK which seems awesome! (I mean compared to the old F5T, it's like WOW!).
