Dim3W Smart 3D Printing Pen released

The Dim3W 3D printing pen was released yesterday. The pen is sort of like the 3Doodler, but with several unique additional features.

The Dim3W pen will cost just $99, and begin shipping next month. It is able to extrude both ABS and PLA filaments.

Just another lame Pen. Is this really any different then the 3Doodler? Aren't there patent issues here for copying off the 3Doodler, or don't they have patents for it?

I really don't get the point of the pens, they seem so annoying and hard to use...
