I have the Razor BW 2013 Ultimate (or something like that). I REALLY like the keyboard, however my wife hates the clickity-clickity of the keys, especially when I am typing a document.
I also had several early failures which Razor was very good about replacing other than the fact they won't do an advanced replacement, which means you are out a week or 2 with no keyboard. I bought another Razor for my daughter so I stole hers, but something to be aware of.
Since the last replacement it's been ~2 years with no issues.
