By accident, I stumbled onto the QuickWeb feature on my HP DM1, while it was crammed into a bag. A quick google search later, I found that pressing F5 (which also corresponds to the shortcut to opening a browser) would boot the notebook into the QuickWeb environment, which is a Linux OS which allows quick access (about 20-25sec) to the Web upon booting.
Tested several websites with the browser, and found most functions working (e.g. Flash, Java, etc). The browser was generally snappy, and easy to use.
As most of my work is done online, this is an interesting option that I may use quite regularly in the future.
