Mention a dual screen notebook and folks tend to look at you like...well, a two-headed monster.
But we believe there is a market for dual screen in a laptop. Acer's new Iconia, a clamshell dual-screen notebook, should soon demonstrate our point (if Acer's unannounced pricing hits the mark). Acer wants to position Iconia as a tablet but we think they are better off calling it a notebook (it's for power users, not the iPad crowd).
We've seen dual-screen notebooks before but it's the clamshell position that we think is interesting for buyers. One 14" screen is in the lid and the other 14" where the keyboard normally goes.
The top screen acts like any other laptop screen while the bottom can do special-purpose: in one mode, the bottom screen continues the top screen image fo full reading of a web page or a document. (This mode seems to be the automatic default function for most applications.)
An optional mode brings up Social Jogger, a dashboard of activity with several social networking sites on the bottom screen. Tap and it opens them on the top screen.
Another app, Scrapbook provides a multi-touch place on the bottom screen to layout your pictures. You can edit/share by tap and using apps that open on the top screen.
When you need to type, the bottom screen can become a virtual keyboard.
The Iconia's multi-touch interface can registering input from 10 fingers simultaneously. Placing both palms on the bottom screen brings up an on-screen keyboard. Acer created an entire gesture library in an attempt to remap the laptop user experience. Acer says they'll release a software development kit (SDK) next month to stimulate third-party development.
Powered by an Intel Core i5 processor, 4GB of DDR3 RAM, Windows 7 Home Premium, Bluetooth 3.0 and USB 3.0, all at 6.2 pounds. Sure, the two screens drain the battery. (Acer says 3 hours, but you know how those battery duration references hardly reflect real life usage...)
Iconia's siren call is the dual-screen. Twice as much display real-estate will appeal to power users. And frankly power uses use notebooks to carry the power from spot to spot, not to power-up in short bursts while running around.
If it were up to us, we'd put an Iconia in every shop window. Twice the bait for shoppers.
