While right now I already have a good phone (N95) for voice calling and 3G and I am happy with the N810 as a internet device - this combination is a pretty costtly combo (even if you replace the N95 with some other HSDPA supporting device).

Just today at the cefeteria the person next to me saw my N810 and asked what phone is that with quite a lot of interest - and was dissapointed that it was not a phone firstly. He liked that it had a big screen and a keyboard to boot - but showed no interest on hearing the lack of phone function.

And this goes for quite a few obeservers who saw the device - and everyone of the common folks out there are looking for a single device with the phone.

So if Nokia does decide to include the Voice calling in the new Maemo 5 based device - I think it will find many more buyers.
