Aside from the sleeve/case...

[Eclipse2xx]

Should I purchase anything else to protect it from scratches/dents?

I just purchased the Wrapsol vinyl wrap since it seems to have very good reviews and has more of a matte finish to it instead of a shiny one like some of the other skin protectors. I also have a WF sleeve for it, but I historically haven't been very good with my laptops and wear watches, etc. which can scratch up the case.
