Should your next laptop be something else?

I always read Walter Mossberg's annual computer buying guide. He's the personal technology guru at The Wall Street Journal, and he writes in a way that even I can understand.

This year, he leads off with a curveball: maybe you need something less than a laptop.

If you're looking for a light-duty, highly portable computer, it's worth considering the iPad, which starts at $499, instead of a small laptop. This is especially true if you're in the market for a secondary computer, or one mainly for use on the go. Many owners of iPads, including me, are finding it handily replaces a laptop for numerous tasks, such as Web browsing, email, social-networking, photos, video and music.

It has superior battery life, lighter weight, and it starts instantly. I don't recommend it for people who are creating long documents, especially spreadsheets and presentations, even though it is capable of those tasks. And I don't recommend it for users who require, or prefer, a physical keyboard.

If you don't like the iPad, there will soon be alternatives, Mossberg writes.

For instance, Samsung's Galaxy Tab, which has a 7-inch screen versus the iPad's 10-inch display, and runs Google's Android operating system, will be available this month from major wireless carriers. Sprint, for example, will offer it at $400 with a two-year contract. But some tablet buyers may want to wait till the first half of next year, when many more models will be available, and Apple will likely roll out the second-generation iPad.

And, as for notebooks:

These low-cost, low-powered little Windows computers are losing popularity, but are still available, typically for about $350 to $500. They are being hurt by the rise of tablets and by light but larger laptops. Some buyers also find the screens and keyboards are too cramped. But these are evolving.

Some now have bigger screens and roomier keyboards. And Dell will soon introduce a sort of hybrid netbook-tablet. Called the Inspiron Duo, this model, starting at $499, has both a regular keyboard and a touch screen that flips around when the lid is closed to act like a tablet.

It will be interesting to see how many people find an iPad under the Christmas tree this year.
