! Warning: this post hasn't been updated in over three years and so may contain out of date information.InfoWorld ran a really useful article yesterday for anyone looking to buy a laptop. The article considered various “optional extras” that many laptops now come with and questioned whether they were worth the money. Draft-N wireless, fingerprint scanners, built-in hard-drive encryption and free-fall sensors are worth having. Solid-state drives, special screen coatings and built-in mobile broadband probably aren’t worth the extra cost.
