Until it breaks and you need to buy a 2nd device to cover downtime (my company gave me a loaner laptop when I had to get mine fixed). And until Apple can address this, a mac is no better than a paperweight when it comes to business.
I work for a multi-million dollar company, and we still have to use the same Applecare service that the common plebians use. While I'm not knocking it, it means that something like a piece of dirt under a keyboard caused multiple-day downtime (and that's with a loaner laptop purcahsed by my company at their own expense), and taking it in to get the keyboard fixed might result in all of your data being wiped. There's nothing business friendly about it.
Dell will come on site and replace a keyboard, no downtime at all except while they're physically working on the computer.
