SAN FRANCISCO  – What would the ultimate full-size laptop need to include to convince you to ditch your desktop for good? Our dual-screen laptop concept merges some of the best tech from Apple, HP, Intel, Lenovo, Toshiba, and others, along with some old-fashioned “if only” whimsy. Read on for the full parts list, and let us know what you think.

Twin, Sliding Screens: These bright, glossy-coated, OLED wide screens support hover and HP TouchSmart PC-style multitouch input; plus full high-def. The left display slides across and closes over the right screen to pack down. Tilt and swivel adjustments are also possible. Back in the real world: Lenovo just announced its ThinkPad W700ds laptop, a desktop replacement with a 17-inch primary display, plus a 10.6-inch secondary screen.

Keyboard and Touch Screen: An Optimus Maximus-style keyboard (each key has programmable OLED displays; pictured) is paired with an Apple-inspired full-width, multitouch, pressure-sensitive glass screen for the touchpad, widgets, and more. The keyboard and screen can also be removed to sit on your desk or even swap positions.

Inside: Intel’s mobile Core i7 CPUs should hit in early 2009; its next-gen “Calpella” platform is expected by year’s end.
Dual Webcams: Able to support multiparty, HD-capable video chat, and optimized for low-light situations.

Speakers: Harman/Kardon stereo speakers with underside subwoofer–like those found in Toshiba’s Qosmio notebooks. We’d also take the SLI graphics, HDMI port and S/PDIF interface from recent Qosmio models, such as the X305.
Blu-Ray Slot Drive: Able to burn BD-R and BD-RE discs at 8X;supports DVD±RW, too.

Would you want it to be inexpensive like a Netbook, yet elegantly designed like a business-class ultra-portable? Would it boast a Gobi chip for wireless data (able to switch between EVDO and UMTS/HSPA); what about dual-screens like the One Laptop Per Child concept design (pictured)?
