I just thought i would forward this to everyone and show why Pre is better than those Andriod devices.
"A major bug in the Android DHCP implementation has forced network administrators to (effectively) ban the use of such devices on the Princeton campus. In the last few months, Princeton has had to kick more than 400 Android devices off the campus network for using IP addresses well beyond the allotted DHCP lease (to the detriment of other users), sending invalid DHCPREQUEST messages after lease expiration, and a variety of other wacky behaviors. The link provides a clearly documented explanation of the buggy behavior, as does this largely neglected bug report. Without doubt, this buggy behavior is affecting other, less vigilant networks, and disrupting Wi-Fi traffic for Android and non-Android devices alike."
