Two manufacturer refurbished units on sale from separate retailers, $330 and under
The Asus Vivobook was announced as the "Touch[screen] available for everyone". Right around the time Microsoft released Windows 8 last year, Asus came put them up for sale. They're meant to be a light and portable machine with an 11.6-inch multi-touch LED display, but also packs enough punch w/ it's Core i3 processor to beat out your basic Pentium processor laptops. The basic unit was $499 at release.
Now, if you know where to look, they're in the bargain bin. Today two cheap manufacturer refurbished Asus Vivobooks popped up from two different retailers:
Asus Vivobook Q200E-BSI3T08 Touchscreen Core i3-3217U, 4GB RAM (Refurbished) — $329.99 at Groupon. Cheapest ever by $120. Next best is $430 at Best Buy.
The above $330 unit comes with an Intel 3rd generation Core i3 processor! It's hard enough to find a Core i3 laptop under $400, make it a touchscreen and you're often looking at $450 and up.
Asus VivoBook Q200E-BHI3T45 Touchscreen Core i3-2365M, 4GB RAM (Refurbished) — $299.99 plus $5 shipping at Woot. Next best is $340 at NewEgg.
The above unit sports an Intel 2nd Gen Core i3 processor, which isn't the latest and greatest but certainly powerful enough for all basic Facbooking/word processing needs.
Both come with 90-day Warranty's.
