Splashtop is a mini-desktop Linux distribution that's based on the 2.6.20 Linux kernel. Currently, Splashtop comes pre-installed on pretty much all ASUS motherboards and on netbooks and laptops from ASUS, HP's high-end VoodooPC division and Lenovo. Rumor has it that Splashtop and similar baked-in desktop Linuxes, like Dell's "BlackTop," aka Latitude ON, will soon be appearing from other PC and motherboard vendors. I wouldn't be in the least bit surprised if DeviceVM makes some new partner announcements at this week's CES (Consumer Electronics Show).
The concept behind Splashtop and its competitors is to make it possible for you to open your netbook or laptop and be able to get to work in five seconds or less. It's not a Windows replacement idea. Most of these systems come with Windows pre-installed as their main operating system. Instead, vendors are addressing the needs of today's hurry-up-and-go users. These folks simply want to get to a desktop quickly so they can check their e-mail, make a VoIP (Voice over Internet Protocol) call or check a Web site, and then close it to catch their next flight.
Splashtop does this by launching from a Core Engine. This is an embedded "proprietary real-time operating environment" within the BIOS. Splashtop Linux lives in the motherboard's 512MB flash memory firmware. Here, you'll find not only Linux and the required drivers and networking tools the computer needs, but an assortment of useful road warrior programs. Splashtop can be up and working even before your hard drive ramps up to speed.
What you'll see is a task-oriented desktop that's based on the lightweight Blackbox (http://blackboxwm.sourceforge.net/) graphical user interface. This means that the desktop comes with ready-to-run application icons. In Splashtop's case, that includes Web browsing, with a version of Firefox; VoIP with Skype; and the universal IM client, Pidgin.
None of this is extraordinary. In fact, the open-source programs tend to be older versions. Of course, Splashtop isn't meant to be be a full-out desktop replacement. Its purpose is to give you just enough desktop to make fast, efficient use of the Internet. From that standpoint, Splashtop is a winner.
