You completely misunderstand.
Example - I want to send myself news to my kindle every day..
I set up a program such as calibre to automatically download news, convert, and mail NYTIMES-MM-DD-YY.mobi to
myname@kindle.com
NYTIMES-MM-DD-YY.mobi arrives wirelessly to my kindle (unconverted)
Am I to understand that this would be free over WiFi? So if i had a conenction at home/work/school/some random place it would be free? But if i want to do this on 3G it would get bounced back?
I honestly haven't tried @kindle.com with 3G yet. But I thought you can use .mobi/azw/tpz files to just xfer them wirelessly. Am I incorrect?
And BTW I would have happily bought a 3G+WIFI version of the DXG (how much could WiFi chipset cost, 20$ tops?) if it was available, but it was not, so I had to shell out 400$ for a non-WiFi version, because they were too lazy/cheap to reapply for patents/FCC ids. I mean, I can understand that the DX models probably do not move the amount of volume to warrant it. And the only difference is the button layout, so who cares other than a needless WiFi feature. Instead they just slapped a new screen in (which doesn't really justify a 200$ price tag difference from a k3 does it? Well maybe it does, but still.
Their inability to add features that could be there by a change in service, such as granting a little more bandwidth to DXG customers since we don't have a wifi chipset would be reasonable IMHO.
If I'm wrong about free wireless delivery // ability to send unconverted documents let me know. But I think it would be a really useful feature.
