I think that all Dell laptops should have the option of shipping with an integrated SIM card reader, to allow for wireless broadband via GPRS, EDGE, and other GSM-ready data services. As well, the laptop could be used as a phone on both WiFi (VoIP) and GSM networks!
A number of laptops, including the XPS M1330 offers an integrated SIM card reader.
