When it comes to mobile computing accessories, size is always a concern. As mobile devices continue to shrink, down to sizes unimaginable just a few sort years ago, accessories need to shrink to keep pace. One accessory subject to use, besides the device, is the power supply, or brick as it is affectionately known, that supplies the power needed to charge the battery. As the battery lifedeclines and the power supply is used more frequently, you will get to a point when you have kept the device long enough that you may need to replace the power supply. If you have looked at the price of a replacement power supply for a netbook or laptop computer, the price can be close to one third of the cost of the mobile device. Such is the dilemma I faced with my netbook. A new OEM power supply is around $120, while a new netbook can be had for $300. That makes the cost really not worth the additional investment. If only the cost were reduced, I could get some additional life span out of my trusty little netbook.
