Over the past few months, the low cost ultraportable notebook space has expanded to include a new class of device. While 10 inch and smaller netbooks are still playing an important role in the field, there’s been a new crop of devices with 11 to 12 inch displays selling for $600 or less. While these laptops including the Acer Aspire 1810T, Dell Inspiron 11z, and Asus UL20A are larger and generally more powerful than most netbooks, as well as more expensive, they’re still a lot cheaper than the ultraportables of yesteryear. And they tend to weigh less than 4 pounds, which is always a good thing.
