Yahoo is the latest in a line of would-be champions to try to topple king Gmail from its perch atop the email mountain. The company’s newest Mail Beta (no relation to Gmail Beta) was introduced last October, but now its overhauled UI and fresh features are available to all. With the change comes quicker load times, stronger spam filtration, and it lets you send and receive Facebook updates and tweets. It also automatically turns picture and video links into thumbnail previews and handles up to 100MB attachments. These fancy new features are certainly a step in the right direction (even if the purple paint job isn’t), but time will tell if it’ll rule the webmail world.
