Question: I was going to buy Windows 7. I know Microsoft was offering discounts for preordering. But I missed out. Is Microsoft running any deals now?

Answer: Microsoft is currently offering 58 percent off a Windows 7 upgrade. There's a catch, though. You also must buy a Windows 7 machine. And it must already run Windows Home Premium, Professional or Ultimate. The discount is for an upgrade on a second machine. The deal expires Jan. 2.

I'm in the market for a GPS unit. I want to enter several destinations. Then, it'll guide me from point to point. Any ideas?

In GPS-speak, this is called multidestination routing. Numerous units will do this.

However, most guide you to destinations in the order entered. You may want multidestination routing with route optimization.

The most efficient route would be calculated. Most manufacturers have units that do this. Prices start just north of $200.

Look for multidestination routing and route optimization in the specifications.
