Interesting article in Computerworld here. On the one hand it appears one can expect just about 2.5 years use of the MBPR before the battery needs to be replaced. This could be an issue for some. On the other hand, for a high-end laptop like the MBPR and all of its benefits, it is worth the cost of $200 to replace the battery when needed or just get rid of the computer and replace it with an updated model. I suppose if the MBPR is a working computer, it is worth the cost. Will this be an issue for any of you? Of course if the battery becomes an issue one could always run the MBPR on electrical power.
