For me a big selling point was the USB hosting. I got a Canon camera for it's great movie mode (as well as an underwater housing). It's great to travel light and having just one camera that can shoot video (which I use a lot) as well as decent stills AND go underwater is just great. But video eats up a lot of memory. The 4 gig card holds about half an hour. Fine for a day or two but on a long trip you need more. Yes I could just stock up on memory cards but better to have some way to offload the pictures to a portable USB hard drive. I'm planning to use the 770 for this.

Oh yes and make phone calls with Gizmo while traveling, internet/web mail to.

It's funny though it seems like USB hosting does not get that much attention. I cannot for the life of me figure out why Nokia does not provide this feature without making us hack the device to get it. And so few PDAs have it (Toshiba is one of the few). Half the people at work have a thumb drive in their pocket so you would think people would be screaming for this feature in their portable devices yet it seems like those that want it are a minority. Imagine you have a file on your thumb drive that you want to give to a friend you met at lunch (too big for e-mail). He has his thumb drive, or even his PDA, with him but how do you transfer? Without host mode that thumb drive is useless. Put another way, would you buy a desktop without host mode?
