do these lights use energy to tell you how much energy you're using?

I think the extra calories consumed by the stress of obsessing over this device will outweigh any benefits obtained from a faster typing rate. :-)

that light is more unneeded power with your computer, and having that to distract you, it's not likely you're going to produce an article faster, and likely of less quality. seriously, send it back to HQ.

So computer use is only green if we're typing (quickly)? What about using our computers to educate ourselves of the threats of (and solutions to) environmental problems by reading sites like Treehugger?

Plus, what if the electricity being used to power the computer (hopefully an efficient laptop) was renewably sourced, so any such reading/educating can be done without needing to buy and/or print out paper-based material?

Or on the other hand, what if the text being written (quickly and efficiently) was climate change denialist propaganda?...

Nah, I don't think I'll be buying one of these.

When the h*** will this site stop promoting rampant consumerism through needless products like this? Stop giving free advertising to companies producing pointless gimick-y products that will no doubt end up in the trash in a very short time. If anyone who reads this site is the least bit 'treehugger', they won't buy this crap.

Agree with the trend of comments; this is consumerist waste of resources. Surely there's standalone software, rather than plastic stuff shipped out of China, that could count speed (yes, it wouldn't glow, or it would glow on the computer's screen rather than a separate glowing piece of hardware, but, c'mon! Do we really need a piece of glowing plastic? Really?)
