I have been searching the net how I can use my Netbook with an internal UMTS SIM card on my LG X110 Netbook, which came running on XP. I just want to use it as a phone using some Bluetooth earset. I haven't found anything like it. Granted operators might not like the idea of using a Data contract also for telephony initially, but an iphone contract e.g. will allow you to do so. Too me it's just a matter of marketeers finding the right pricing structure. And why not have data and speech in one (PC)?
So I turned to Android. All these discussions above seem to overlook the simple fact that Windows XP, MacOS and even Linux (I guess) on an Intel Processor have never considered using their OS for good old telephonecalls

. If Android will be first, this might just be the platform of choice for the next leap forward.
If you have any suggestion how I can reach my goal in the interim or any others comments, I'd be happy if you would let me know.
