What is an ultrabook?
0Ultrabooks are thin and light laptops with Intel processors. That Intel part is key, since Intel coined the term, trademarked it, and works with PC makers to certify certain laptops as “ultrabooks.”
These laptops tend to weigh 4 pounds or less and measure less than 0.8 inches thick. Ultrabooks are available with screens ranging in size from 11.6 to 15.6 inches. They’re larger than netbooks, but typically they don’t weigh much more — and they offer far more computing power than a typical netbook.
Ultrabooks also have a few key features that set them apart from most other laptops, including:
- Either a solid state disk for storage or a hard drive with 16GB or more of solid state cache
- Quick boot speeds and nearly instant resume from sleep
- The ability to periodically poll the internet for updates even when the computer is sleeping
Intel sets a target price for ultrabooks at around $1000 or less, but some ultrabooks have much higher prices while a handful are available for less.
List of ultrabooks
Here are some of the most recent ultrabooks:
- Acer Aspire S3
- Acer Aspire S5
