Microsoft, Google, Linux, forget them all! Instead take all the money you have left and run to the Apple store for your computer. Not only will you end up with a computer that will not enrich Microsoft or Google, but you will join the ranks of the enlightened Such as 1st thru 3rd graders all over the United States. People who have spent so much money on Apple products that they are stuck wearing the same corduroy sport coat with the decorative patches on the elbows and sandals year around. And if this is not enough you will never suffer from a lack of conversation starters (and finishers) since you are an Apple owner.
