I just ordered 2015 m5 MacBook 512gb without even thinking about specs because of the great deal and I only played it at the store for only 2 minutes. I know the screen and trackpad are superb, keyboard was okay and I didn't even think much about it. The only thing that I forgot to see how well it deals with regular tasks. I don't play games, edit video or use any external devices except for portable HDD for occasional time machine backups. I watch movies, browse internet, listen to music, watch YouTube, etc. I hope it is at least somewhat faster than my old MacBook Pro 13" Late 2011 with 2.2ghz i5, 120gb SSD and 8gb of RAM. Or I am wrong? Edit: according to benchmarks it's the same.
