Intel Ultrabooks have begun to hit store shelves. Examples include the Asus Zenbook, Acer Aspire S, Lenovo U300s and Toshiba Portege Z830. What exactly is an Ultrabook? It's a thin and light ultra portable laptop meant to respond to ARM-based tablets (e.g. instant on, great battery life). The Ultrabooks shipping this year are consumer focused. Next year, business-grade Ultrabooks with features like VPro, VGA and Ethernet jacks will start to appear as will touchscreens and hybrids with Windows 8. The comparison to the Apple MacBook Air (also powered by Intel chips) is obvious. Don't confuse Ultrabooks with netbooks. The average price of a new Ultrabook is ~$1,000 while a typical netbook can be had for less than $500.
If anyone has an Ultrabook or considering purchasing one, I'd be interested in your thoughts.
