Splashtop is a proprietary pre-boot environment, developed by DeviceVM, which allows you to rapidly access certain applications without the need to boot your main operating system. Splashtop boots out of the BIOS on your PC motherboard, and launches a lightweight Linux stack capable of running certain applications like the Splashtop web browser, and the Skype VOIP program. The Splashtop environment allow you to open a web browser, check email, watch videos, instant message, and place VOIP calls within seconds instead of minutes.
Splashtop is currently available only on the ASUS P5E3 Deluxe / WiFi AP motherboard. That motherboard is available most places where ASUS PC components can be purchased.
I've old Intel Celeron 1.7 with 512 MB and 3 x 80GB hard disk FreeSAN SAN device. I'm not thinking to get ASUS P5E3 Deluxe and add 3x 1TB to improve my home storage :)
My friend has this board (P5E3 Premium/WiFi-AP @n) and it has some crazy overclocking abilities. It also supports DDR3 RAM.
