Black Friday purchase

I didn't go to any mall but I still spent money.  Just ordered a 13" Mac Book Pro with retina display. Apple computers don't go on sale very often and I have been contemplating buying one for a few weeks now.  Finally, with Ed's prodding, I placed the order. And as typical behaviour for me when making a big purchase, I feel guilty about it. But also very excited to get the laptop and start using it. Is the retina display worth the extra bucks?  I sure hope so.
