I checked the Apple site first thing this morning and saw they had a refurbished 2.4 GHz MBP with 256 vRAM for $1650. I couldn't pass this deal up so I snagged it. How has everyone's experience been with refurbished? Is it gonna have little nicks and scratches on it, or does Apple replace these parts that show usage? Also, is it gonna boot up like a brand new laptop with nothing left on it from previous user? One more thing, if I have an Apple certified repair place install a bigger hard drive in it, will this void the warranty? Thanks!
