Comment on Screen Calipers

Jeezaloo... $30 for calipers? Don't they know that the Art Director's Toolkit that COMES with OSX has a measuring device in it?

Oh, you have to pay to be able to rotate it. Wow. Just stretch the ADT ruler edges. It measures the diagonal distance, AND tells you the angle. I officially can't see a use for this program. Ever.
Try it. Pop open the ruler, change it to measure pixels, line up the edges, and viola. Horizontal and vertical alighment in a snap, with a cleaner interface, and for free. True, there's no compass... but hell, I could probably code something like this in approximately zero time flat. The skinnable interface would be trickier, but that shouldn't be the selling point of an app anyway.

After poking around on the site a bit, I have to admit they do have some good tools... but the prices are flat out rediculous. All 3 combined might be worth the money. They'd probably sell more if they sold all 3 at $20 (then people who needed to measure things actually WOULD buy it, instead of just the (evidently) stupid ones).
