I by far prefer the controls on the Lenovo for editing documents to what is available on Macs. I find the Mac too dependent on gestures whereas there are more physical controls on the Thinkpad and the trackpoint is where my forefingers are when typing so I don't need to move my hand to use the mouse. Perhaps I naively assumed any modern computer is fast enough. Anyway the Thinkpad is brilliant for writing.
I whole-heartedly, concur. Furthermore I have been a fairly faithful user of Thinkpad laptop products for nearly twenty years, principally models tailored to business and image-processing, in part due to my early experience with IBM Selectric typewriters and CRT workstations at school and work.
As my own interest in photography evolved during the nascent digital age, I eventually migrated to the Lenovo Thinkpad workstation laptops, to great effect. For several years, the model W500 met my needs; replaced relatively recently by the W530 which, although not the most recent or improved upon offering, I'm still finding a very capable platform, handling 24 megapixel NEF files without issue. (Your mileage may vary -- as we say in the USA.)
I'm sure that whatever form or functionality Nikon's new product reveals, a suitable business-class, professional usage, Lenovo, Apple, HP etc mobile device will meet that challenge.
