Oh my God, if it comes on wheels, I want it. No questions asked. I've ruined enough hardwood floors (and fingernails) doing the dreaded push, pull, tug, cry, and scream. It's not that I'm labor-averse, just lazy. And eager to be mobile.
A pretty cool bookcase to zip around the house. For $199, the Go-Cart Bookcase is not a bad deal either. Great for teens and adults alike. Sturdy and clean lines.
