Well considering that the purpose of the model A is just to get Kids interested in programing again a lot can be accomplished with a keyboard by itself, or at worst a keyboard with a usb port (shot even my monitors come with USB ports now days
) As for the Model B don\'t you think you\'re going a little over the top here?
As I keep saying there are 5 pis I\'d like to get over time
1) Media Center for TV (uses 1 ethernet port 1 USB for combo wireless keyboard with built in trackball)
2) Web server (uses 1 ethernet port, nothing else)
3) NAS (1 ethernet port, and 1 usb for external drive, I can power it off AC adapter or if I really wanted to use an external USB wall wart which is a lot cheaper than a whole hub just for 1 device)
4) Experimentation device (sudo desktop replacement, uses 1 ethernet port and two usb ports for keyboard/mouse)
5) Portable e-reader or possibly mobile computer (e-reader would use model A with one usb port used for wi-fi
Let\'s go ahead and throw in a number 6 web filter (uses 1 ethernet port and 1 usb for additional ethernet)
And let\'s also do a 7th for older console emulators (sega/NES/SNES/etc) this is the one device I\'d want a powered USB hub for and that\'s just so I can have four players
Now I say all this because there\'s a lot of doom and gloom going on about the lack of USB ports and while I want to emphasize that I fully agree there are some applications where more ports would be nice, if we stepped back and thought about it, most of the application we\'ve been talking about using them for just don\'t need the extra port. Yes, some do, but should we universally increase the cost of the board so that 1 out of X numbered board can have that one extra port they need?
I also confess that I wish the USB ports were capable of providing a full 500 mA of power if the wall wart could supply it. I think that would solve a lot of issues, but even then, the main issue most of us will face is powering those travel drives (I haven\'t seen in 3.5 inch drive enclosures that could powered off USB) and a better solution than a powered USB hub would just take the extra USB plug and snap it into a USB wall charger. With phones using those now days, many of have extra ones lying around that could provide enough power and they\'re cheaper than a while USB hub if you have to buy it out right.
