This isn't an analysis piece, it's a hatchet job.

Ashley you do seem to take quite an opinionated position with this article. It sounds like you're condemning google glass already, especially with comments like:

I would recommend not reading or commenting on Google Glass articles, if you're not interested in the device. You should probably also elect not to purchase one.

The fun starts once you add The Culture to that chart. xD
GSVs are generally around 300 kilometres long, GCVs about half that.
Now, relatively speaking there's very little mass inside a GSV, as they're mostly force-fields, rather than metal hull, but they're still monstrously massive spaceships. And very fast and agile…

Even if you are right, you're a dick.

Why would anyone buy Only a heart rate monitor that costs as much or more than a heart rate monitor with a wearable display (ie, a watch) and GPS tracking? This product makes no sense at all.
