Very much so. When she (my wife) was first looking at getting one I went down the whole "maybe you should get an X, Y, or Z instead..." and then began thinking about her having to learn a more complicated design package, seeing how cheap some of the different Cricut tools can be when bought on sale, and I realized that it probably was just fine.
Sure, it's not a pro level device, but it did allow her to easily get shapes cut out of vinyl or cardboard or whatever with very little ease. The software worked for someone without a background in traditional design software. And it really didn't cost that much.
Few years on she still uses it, it works well enough... And that's it.
I sometimes/often think/realize the HN crowd falls hard into the technical perfect-is-the-enemy-of-good, and a number of the replies here clearly illustrate that.
