Yeah, Bill's a dick. He's letting that "man of the year" crap go to his head... now he thinks he can belittle everyone elses efforts to help people without a lot of money.
"The last thing you want to do for a shared use computer is have it be something without a disk ... and with a tiny little screen"
Gee... lets put a disk on it, increasing cost and, more importantly the power consumption, immensely, and making it shock sensitive, dust sensitive, heat sensitive, and software breakable (even Linux can be messed up with rm -rf /). Oh yeah, that bigger display is also going to raise the price and power consumption.
If Bill Gates can make a better $100 laptop for the target audience (without it being a loss leader, like the X-Box), fine. Until then he should just STFU.
