doesn ' t get anywhere close to 10 while actually using it . 10 hours is facebookingiTunes . Not sure why anyone would argue for a smaller batteryHave you seen Chrome ' s battery use ? Have you seen Facebook ' s amount of code ? Facebook and iTunes is significantly higher load on the battery than what I spend most of my day doing , which is running VMs and writingrunning Python code . People shrug off websites as idle or useless time of no consequence , but if you ' re running Chrome and a lot of people do a Facebook tab or two is a significant drain on battery and I ' ve seen Chrome tabs taking up 1 . 5 GB of RAM or more , so it ' s not just battery they ' re wasting . it ' s got significantly less travel . Whether you personally prefer it or not doesn ' t change that factSure , but it has less travel isn ' t proof that the keyboard is markedly worse . It ' s a matter of preference . Again you are only talking your personal opinion . Like I said before , you are in the minority thinking the rMBP was a backbreaking machineI never said or thought it was back breaking , just that a decrease in weight isn ' t a pointless change .
