A great why to find advantageous companies is to look at those driving key technology market trends and generating good business results when the rest of the market is struggling. This story fits Synaptics, the touch-interface specialists, perfectly.

Synaptics makes human interfaces (mostly touchpads and touchscreens) for a variety of PC and smartphone devices. Big customers include Dell, LG, Ericsson, HTC, and Sony. The company has grown fast, roughly doubling revenue and earnings since 2007, at a time when the economy has been dark, at best. During this time, the stock price has been volatile, but largely flat, and the stock price relative to earnings has gotten cheaper and cheaper.

The company announced earnings yesterday, reporting net income of $19.3 million, or 54 cents a share, compared with $12.4 million, or 34 cents a share, a year ago. Synaptics earned 70 cents a share. Revenue hit $145.8 million, a ries of 27% over last year.  

If there is a technology guru and review who can make a break a technology's future with a few keystrokes, it's Walt Mossberg. The veteran gear reviewer for the Wall Street Journal is now out with his take on the iPad, and he calls it nothing short of revolutionary. Oh boy. This should uncork any remaining iPad hype that hadn't already boosted the press  into oxygen-depleted zones of the atmosphere.  The iPad is now akin to the discovery of the wheel.
