The 2009 iMac isn't worth repairing, so the wife & I are looking into getting a notebook. This would be our family's main machine for kids', homework, professional conferences, iPhone/iPad backups, iTunes, photos library, etc. Looking to spend around $2,000 & an SSD of 500GB-1TB is non-negotiable. What's the best machine we can get for around that amount? A new MBP? New old stock? Refurbished? Used?
