Jon Brodkin, reporting for Ars Technica:In a time when consumers routinely replace gadgets with new models after just two or three years, some products stand out for being built to last. Witness the Linksys WRT54GL, the famous wireless router that came out in 2005 and is still for sale. At first glance, there seems to be little reason to buy the WRT54GL in the year 2016.
