As many as 15 netbooks (engineeering samples) were distributed amongst ARM executives last year.
Bob Morris, director of mobile computing at ARM, descriobed his first impressions in his blog. http://tinyurl.com/matrdx
Bob's was a 10.1-inch netbook with an 800MHz Cortex-A8 processor.
He got 4.5 hours life on a two cell battery with"screen at full brightness and Wi-Fi on".
Fair to say he was impressed.
