I don't understand why the next tablet will not be able to make regular 
phone call, since it will have 3G link. It's a non sense. Of course it's 
possible to use SIP over HSDPA, but it's not a service that provides 
well know operators (at lest in Switzerland) where the vast majority of 
people already have there usual number (maybe this will change in the 
future). I hope the HSDPA is not the only protocol of the next tablet as 
there is still vast area where only the GSM signal will be available. 
And from my experience, I doubt that even the 3G IP link have acceptable 
quality of service to pass a SIP call if your are not is near ideal 
condition compared to a regular call.
