I'm thinking of buy a Lenovo Thinkpad X230 for $225. I own a copy of Linux in a Nutshell 5th ed. which I bought for 25 cents at a goodwill. Is there any advice or suggestions someone can give me before I pull the trigger? I am a beginner in linux, although I did get mint running on an old laptop a few years back.

edit: I ended up buying a Thinkpad x250. I am excited.
