I purchased mine in November. After letting them thrash about for months they are sending me a new machine off of the line. They offered a refund, but darn, I like the machine. I can't find anything comparable out there that has a sufficient service contract to meet my needs. I thought about a MacBook pro running windows but am given to understand that the battery life is not optimized in that scenario. I'm comfortable wtih the Windows OS, so why should I bother to become aware of all of the nuances of anything else? too busy for that... i'll let you know how the new xps 15 works out.
I expose the system to lots of different wireless environs due to the fact that I travel 200 days out of the year.
