While that's all well and good, the big news with the Asus B43 and B53 is their support for Boston-Power Sonata batteries. These next generation lithium-ion batteries, already found in select HP notebooks, are said to offer triple the lifespan of typical notebook batteries. They'll reportedly keep 80% of its initial charge for 1,000 charge cycles -- compared to 300 cycles or less for conventional laptop batteries -- and are able to recharge to 80% capacity after only 30 minutes.
All models come with a durable aluminum casing and spill proof keyboard. Other enterprise-friendly features include Intel's vPro, anti-theft, and trusted platform module technologies, docking station support, as well as fingerprint and smart card reader support. The Asus B53 is expected to be available immediately for $1,100 in its most basic configuration, while the B43 models should be a little cheaper, but their price or exact launch date is still unknown.
