On the desktop I think transfer speed has a lot to do with hardware and system software, on the best systems there is little speed difference between FW400 (FW800 is a rarity) and USB2 (I have both on all my desktop machines) but eSATA eats both of course (I have a few external drives with eSATA, USB2 and FW400 so it's pretty easy to compare). -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Or is the GPS h/w itself the battery hog? http://preview.tinyurl.com/34blok2 Looking through the web site (which sucks BTW) I found that it's not really GPS. It's something called WPS that uses nearby wi-fi networks to generate the location data. It captures data on nearby accessable wi-fi MAC addresses and adds them to the photo for uploading to Eye-fi's site. Once the photo is uploaded to their site, the MAC addresses are compared to the "known locations" of MAC addresses in their database and the long/lat are triangulated from those and downloaded to the card in the camera for addition to the EXIF. So I guess the answer to your question is the wi-fi can't be turned off independently and the "GPS" itself is the battery hog.

That's not really how it works. Eye-fi uses skyhook's database. There's an explanation of how that was created here: http://www.skyhookwireless.com/howitworks/ In Igor's example the photos would be tagged as being taken in Houston, even though the Wi-Fi wasn't free. All eye-fi needs is the Wi-Fi hotspot's SSID to determine location. At least, as far as I understand it. Eric.
