I'd have to agree, if I had a cricut, I would probably not have been swayed to buy a slice. But last birthday, getting the slice was exciting! At $150, it was more affordable than all of the other cutting systems I knew about and had a great portable size. Since I'm doing more and more crops I love that it is a small size to take with me.
I do both cards and scrapbooking and would love it if I had a system that did 12 inch long title block size things but I make do. Most of what I do with it the 4" size is fine.
