I just want a reasonable explanation why Microsoft made a requirement that Windows Vista Home Basic Upgrade, when installed from XP Pro, has to format the hard drive in order to install. A PC can boot from the Vista Home Basic DVD, then tell you it has to be installed from the desktop. Once at the desktop, it tells you it has to wipe your hard drive. Absurd!

If Win7 has an upgrade, and I can't see why it wouldn't, I really hope it doesn't include such a rediculous requirement.

At least for the proof of concept stage, they might want to make a light source that consumes significantly less juice than an LED, and has a greater tolerance for fluctuation.

From Wikipedia:

"LEDs must be supplied with the voltage above the threshold and a current below the rating. This can involve series resistors or current-regulated power supplies." http://en.wikipedia.org/wiki/Led#Disadvantages

Using an LED as an example of what this tiny power souce can't power seems futile at this point.
