Re: Charger? (was: Re: FreeRunner Pricing and PVT update)
I think I'm going to have to completely disagree on this one. I RARELY plug anything into a computer to simply charge it. I'd venture almost never. The idea that I HAVE to plug a device into a computer to charge it is completely ridiculous to me. I'd bet my experience as a product marketer that consumers would feel similarly. My expectation of a cell phone (based on precedent) is that I get a wall charger with my phone. Even Apple didn't break this precedent with the iPhone. You can plug it into a cradle (connecting to a system), a wall charger, or a vehicle accessory charger. That being said, I don't know whether this custom charger is just a modified USB cable or an actual wall charger. Again, based on precedent, my expectation was that it was a wall charger. Thinking about it now I realize that perhaps that was not a good assumption to make. Just my 4 1/2 cents.

Re: Charger? (was: Re: FreeRunner Pricing and PVT update)
Reading your email I wonder if there is a misunderstanding here. A USB charger is not a device that gets plugged into a computer but it is simply a device that supplies power on a USB-like plug. It can be a wall charger or a car charger. If you go to ebay and type in usb charger you get plenty of hits starting from a few dollars. The only and minor issue is that these chargers don't speak the USB protocol and thus can't say hey, you can take as much as you want and I'll give you as much as I have. They simply offer voltage and current on the plus and minus lines of the USB plug. So essentially the Neo asks hey, can I have 500mA? and there is no answer. The Neo then plays safe and pulls only 100mA as to the USB standard. But the Neo can pop-up a dialog asking you hey guy, there is some unknown charger, I currently take only 100mA, shall I pull more anyway? - and this lets you use *any* USB charger out there. Be it one from Apple or one from eBay. best, marcus On Mon, 2008-04-14 at 00:57 -0700, Lowell Higley wrote: I think I'm going to have to completely disagree on this one.

Re: Charger? (was: Re: FreeRunner Pricing and PVT update)
Well, you'll get used to it :) USB-Charging is fine. You can use a standard usb-wallcharger as well as any mini-usb cable or usb-carchargers and so on. I have some devices that can only be loaded over usb and some who can also use a proprietary charger. I mostly use usb, because I have a dozend chargers for that. I agree that a charger should be included, but at least we have to know if it will. Also there's still the fast_cccv issue, means you have to explicitly allow the device to charge at a high rate if the charger isn't a usb-host. As there will be no charger included, I think this should be activated in the official distribution by default to allow charging without hacks. It should also be clear, that there is warranty for this method of charging, as there is no officially allowed solution included.

I think my main concern is I see USB Cable and USB Charger used interchangeably in these messages. They are not one and the same. So which is that we are talking about?
