512GB / 16gb ram / i7 2.7 ghz quad core / silver Coming from a 2012 macbook air and need to get something that will hold up well for at least 6-8 years. Most intensive uses are internet and word processing, occasional mucking around w/Photoshop. Thats it. I know these specs are huge overkill but then again, not everyone who buys a ferrari drives it at top speed every minute of the day. Any advice/comments?
