You can both be correct depending on sampling.

UK Birmingham: 0700 trains to London (corporate types), Thinkpads, Dells and a few HP laptops all with Excel/Outlook in operation. A few hours later (students and younger people), it changes to tablets and Macs. Mostly watching films or doing Web stuff. And lots of phones.

I'd imagine a large percentage of Windows licenses in any country are for desktops sitting in offices (1000+ in my fairly small organsation alone).

People use more Windows laptops than Mac laptops everywhere. Apple's marketshare is like 25%.

Way lower than 25% actually.
