This tends to be the time of year I got a lot of questions from parents of recent graduates about what computer/phone should they buy. Buying a new laptop can be a challenge for many folk and we often worry are we getting our moneys worth. One resource I highly recommend for those looking at purchasing an Apple product is MacRumors Buyer's Guide.
This website can give you helpful hints on if you should purchase the current MacBook or iPhone or maybe what a month and have the chance at buying the latest version (or the previous model for a cheaper price).
Also, if you are looking at purchasing a Mac for a graduate or yourself, you can save a good chunk of change by buying from Apple's Refurbished Store. Normally people tend to stay away from refurbished items, but buying straight from the Apple Refurbished Store is a pretty safe bet. Apple holds these machines to a very high standard and still includes a one year warrenty.
