Depends on your definition of issues though, I prefer linux to be perfectly honest but the MacBook Air I have has changed my mentality about battery life.

I literally do not look for outlets anymore; I use the machine for the whole day and I charge it at night like my phone.

If that's what the competition is then the 5hrs I used to get with my 97Wh battery on my Precision 5520 is definitely "an issue", because 3.5hours in I start getting battery anxiety.
