Hear you there; but keep in mind Apple could have limited the use of the USB port for things other then competing 3G network devices.
For me, I lament the lack of an SD card slot over the lack of a USB connector... I see this as Apple's game to get us to buy the 32GB or 64GB models. Why offer an SD card slot to expand beyond the basic 16GB unit if there is no built-in expansion?
I am not sure what is worse a restricted USB port or no port at all.... though memory card wise, it might be more sensible to allow browsing of say images & videos only and restrict storage of apps ibooks and the look to the internal memory, I can buy that kind of restriction as in theory it should make the device safer... that being said, i'm sure Apple would be ridiculed anyway.
There is that article on Computerworld.com critical of Apple for the 3G cost given the component costs less than $10, so it looks like they are subsidizing the non 3G versions. I agree that a usb 3G device isn't elegant, but I can see the people who already have one and are paying for the monthly service would benefit more from switching it between devices than adding yet another service plan... (based on AT&T).
I wonder if it would be possible for Apple or another company to create a connector that allows charging & have a second shorter cable hanging off for connecting memory cards?
I really want to like this device because we have needed a truely functional tablet style device for a long time, but imposed restrictions for now seem to make it just another tablet unfortunately.
Probably also another example of Apple keeping quiet while the rumour mill goes insane coming back and biting the on the butt. Free talk is great, but there were pretty high expectations set and quite a few got missed.
