That's right.

Like you, I don't WANT the N8x0 to have built-in cellular because I don't see the point of having a second SIM to juggle around, or another subscription plan to pay for.

Case in point: some of us have unlimited data plans with our voice plans, usually as a company phone. The last thing I want is to have to switch my SIM from one device to another (don't even get me started on how useless a TwinSIM is, i.e single MSISDN, dual SIMs) and have my data all over the place, out of sync.

Right now, my contacts and calendar data stays nicely on my phone, and my N800 connects to the internet using BT DUN to HSDPA/UMTS.

My phone stays as my phone, and my tablet stays as an accessory to the phone. That's why laptops with built-in slots for HSDPA haven't exactly been flying off the shelves.
