My Mom is currently using an old Thinkpad laptop running Windows Vista. It works fairly well for her, but today was the final straw. I just got finished hooking up a new printer for her, but I had to spend several hours getting the drivers installed properly. Meanwhile, my MacBook Air was printing with no configuration whatsoever. She's been a PC/Windows user for her entire life. However, she does see the benefits of the Mac and is considering switching to have things "just work." Since she's a very light computer user who needs a ~15-17" screen just to read text, and all she really needs (IMO) is a Mac capable of running OS X Yosemite. With this in mind, I figured that a Mid/Late 2007 - Mid 2009 MacBook Pro 15" would be a suitable machine for her. We really don't want to spend much money, but I'm hesitant to buy a Mid/Late 2007 MacBook Pro or an Early 2008 MacBook Pro because of the massive problems people have had with the GeForce 8600M GT. Is a Mid/Late 2007 MacBook Pro 15" reliable enough for a light computer who simply wants something that "works" and doesn't want to pay an arm and a leg? Thanks.
