    There's this article but then it'd only work if it could see known wifi hot spots?

    Wi-Fi Positioning System (WPS) is a term pioneered by Skyhook Wireless to describe its Wi-Fi-based location system. Skyhook has built and maintains a large global database of Wi-Fi access points and their precise locations. This data may then be used by a mobile electronic device to triangulate a user's position.

    WPS may be combined with cell phone tower triangulation and GPS to provide reliable and accurate position data under a wide range of conditions, including among tall buildings and indoors, when GPS signals may be weak or intermittent.
    Limitations: WPS does not work when out of range of Wi-Fi signals, and the Wi-Fi hotspots database must be constantly updated to keep up with Wi-Fi hotspot changes.

    ok so from what I'm reading so far....

    WIFI only GPS - Ipad wifi
    Skyhook and others are driving round the world noting the position of wifi SSIDs and the co-ordinates. These are then saved to a database to be used by wifi devices for postioning. Accurate if your location has been scanned in the db.

    Ipad 3G
    has satellite GPS + Assisted cell tower GPS + wifi GPS

    A-GPS (Assisted GPS) on iPad 3G/iPhone 3GS goes a step further, finding the closest satellites to more quickly identify your position. If you’re not within a clear line of sight to a GPS satellite, iPhone finds you via Wi-Fi. If you’re not in range of a Wi-Fi hotspot, iPhone finds you using cellular towers. The size of a location circle tells you how accurately iPhone is able to calculate that location: The smaller the circle, the more accurate the location.

    Now that I've actually read your post a little closer, I didn't really answer your question.

    No, I don't think the WiFi model has the GPS chip set. At least according to Apple it doesn't. Does this mean that it doesn't REALLY have it. Not sure. :unsure:

    However, it does do a bang up job of finding out where you actually are! :thumbsup:

    I dare say the 3GB per month would be best for most people - I used to use a virgin media usb dongle, and never exceeded 2gb per month just browing.

    I guess this is a direct competition to the laptop+ usb dongle? If this works well, do you see them offering it to macbooks?
