That is pretty neat--GPS and Wacom tablet included. Bet they're glad the Apple tablet rumors weren't true!<br><br>nagr[color:red]o</font color=red>mme<br><br>I require stroyent!<br>TeamMacOSX.com | MacClan.net
This points out how cheaply Apple could add GPS receiver ability to the iPhone or laptop. One can buy GPS receiver with this up to date SiRFstar™ III chipset for all of 25 dollars. For the 25 bucks you get a bluetooth enabled gps, a powercord, a manual, and a CD of software so you can place the dongle in your car and then receive GPS on any bluetooth device nearby. But if that chipset were imbedded inside the iPhone or laptop it would be much cheaper than the 25 bucks because that would delete the necessity for the bluetooth chipset, the manual, the powercord and the software CD. Likely you can buy that chipset in volume for about two dollars. This is a very low power chipset. It would add nada for power consumption especially if it was on the motherboard. Apple will do this sooner or later. Wish it was sooner.<br><br>It would also add pretty good theft protection if you wanted it. A software add on to intermittently send the laptop GPS position out on available wireless to you other computer would be easy. You could find out quickly where your laptop went if it left the library without you. <br><br><br><br><br><br><br>
Someone stated in another thread somewhere that GPS would drain the battery on the iPhone fairly quickly though... which is probably why it isn't in there.<br><br>The Graphic Mac for your Mac and graphics news, tips and more.

They were using old information. The GP chipsets have been very low watt for years now. If you remove the color screen and all the memory access in a standard mobile GPS and just look at the watts needed to run the chip set and acquire a signal with a patch antenna it's next to nothing. It's so cheap, small and low power that they slap GPS on mortar shells now. With a some extra servo motors and fins the shell can be guided on its way. Mortar shells spin rapidly. No double AAs required. <br><br>
Just looked it up. That GPS chipset consumes 50 milliwatts when used to acquire 20 simultaneous satellites. That is 1/20th of a watt. The watch on your arm may consume more.<br><br><br><br><br><br><br>

The ability is built into the CDMA network, but not GSM. I know when I'm using the navigator on my verizon phone, the phone has an active link to servers, but it can run hours at a time and not drain the battery. Like it's passively receiving from the towers instead of transmitting. I can't talk a 10th of the time that I can use the GPS.<br><br>Perhaps the GSM phones can't passively receive information needed, and have to maintain an active connection using the phones transmitter, so it's not the GPS that's draining the phone, but the connection the phone has to maintain while using GPS? I dunno, I gotta go look that up again.<br><br><br><br>Hey I'm an F'n Jerk!®
