Yeah, definitely, like Sanara says, you'll be buying things that are not in the kit & you'll run out of things (I've already spend lots of money on typodont teeth & burs & scalpels, oh and of course, those really expensive textbooks).
We asked the school why we had to buy a laptop this year, and the school told us we needed it for the histo CD which was a really lame answer IMO since there are computers in the histo lab and you can view it else where when you're studying for histo. I'm sure it's good for people who don't have any kind of computer, since it's important to check school e-mail and such. In any case, the laptop is needed when we start going into clinic because the school is going to be computerizing patient data base & things (it's in the process of converting, I think).
