FYI - USB stands for Universal Serial Bus.....the cords work in lots of different things. The one for your printer should work with your cricut. The camera...well, the end that connects to the computer is all the same, but for some reason, the part that goes into the camera is different than the one that goes into the printer.
IF you go to Cricut.com and check out the section for Design Studio Software, you can see some of the amazing stuff they are creating with the software. Not just welding letters, they are creating frames, wall decorations, borders, full page layouts, and card designs.
I am green with envy as I have a Mac and can't use the trial - at least for right now. DS has promised to get it to work on my Mac with an emulating software after the first of the year.
