I've been thoroughly enjoying my silhouette since I got it this last summer. Have done tons of projects with it (and people begging me to cut stuff for them, too), and now I'm even doing my December Daily with it! I use it for print and cut more than anything (simple white card stock paper that I can get around here).
One tip for the print and cut:
I've never been able to perfectly align my printed designs with the cutting machine (done all the registration marks and stuff), and I haven't been able to figure out the alignment tutorials that are out there for the silhouette (they don't really explain things well enough for me to understand it, lol). But I've been printing and cutting every day recently for my DD project, and I found that things work far better without the registration marks. I usually add 3 little dots to my paper before I send it to the printer, which I then use to align the designs for my cutter. After printing, I usually have to move the entire page up 2 notches, and 1 toward the left using my keyboard's arrow keys (doing a quick test cut with 1 of the 3 little dots to see how much I need to adjust the position), and more often than not the designs align perfectly with the cut (though I still give them a little bleeding space just in case). Works perfectly for me, and I can save paper and ink by not having to go within the limits of the registration marks ...
Maybe I should do a little tutorial on my blog to show what exactly I mean (coz I'm not sure I was very clear at explaining it the quick way here). But at any rate, I'm happy for you that you get to enjoy the fun of having the silhouette! Yay!
