I upgraded from a 13″ MacBook Pro to a 15″ MacBook Pro a few months ago. I also started using one of my old laptop cases as it fits the 15″ model perfectly. Don’t worry, I’ll go back to the LL Bean backpack when it’s warm enough to bike again. However, as this case is about 7 years old, it has an extra pocket on the side for a phone. Not a smartphone – just a regular flip phone. I’m an iPhone user so this is of no use to me. Actually, I take that back. I’ve put it to good use as the place where I store my morning snack.
