Nokia and Intel (who were together developing HSDPA for the new Centrino chipset) decided there was no business case.

Considering most laptops have Bluetooth built in, isn't it easier to Bluetooth the laptop over to the mobile phone for internet connectivity? In fact, precisely how one connects an Internet Tablet to the cellular network - using Bluetooth. No need to put an extra SIM in the laptop and no matter if the phone supports WCDMA/GPRS/GSM/HSDPA etc the laptop can connect to the network without a hitch - brilliant.

Building phone functionality into devices that each then need their own additional contract with the network provider makes no sense at all to me. There may be some side benefits from having the phone functionalioty integrated but these are few and far between - most users won't care about it. I guess Intel + Nokia realised that too, eventually. And besides, SonyEricsson just released an HSDPA PCI Express card which addresses the tiny fraction of users who are interested in HSDPA in a laptop/UMPC device.
