You may argue that Windows-machines come with the ability to change out the battery - but the number of people who swap packs on the move is low. I've yet to be caught short at an all-day event with my Mac, and this was a continuous problem when I was using a Windows machine. All the apps which I use the most on my Windows PC. The experience is a hell a lot better than what it is on Windows today. are synced seamlessly between all the devices. Photos, contacts, calendars, reminders, notes, messages etc. What the figures also show is that even brand new. On a Mac, you just sign in once using your Apple ID and iCloud takes care of the rest for iOS users.

The closest Windows machine is the Lenovo Yoga Pro 2 and it's three hours short of this figure (7 hrs 10 mins). Windows 7 is the outright winner, though, with a 46.64 per cent share more than Windows 8, 8.1, XP, Vista, Mac OS X 10.8 and 10.9 combined. Mac OS X provides better battery life than any comparable Windows machine.The MacBook Pro 13in is unbeaten in our Iron Man battery life test - clocking 10 hours and 27 minutes of usage. Lenovo has tried to one-up Apple by using a 3200 x 1800 resolution in its Yoga Pro 2, but Windows 8 isn't able to scale up and use all these pixels - so it can't make full use of apps.

Windows OEMs are a generation behind when it comes to screens. Apple has helped push the tech world forward introducing Retina Displays, and discarding spinning disks in favour of faster PCIe-based flash storage.
