Hm, there seems to be a problem at least in the english version of the notebookcheck.com. On the homepage there's a recent link to this article which says February 2017 update in the preview paragraph, however, when I click the link it goes to this page, where it says January 2017 update. Hasn't been translated yet or pointing to a wrong article?
Maybe you haven't reviewed this yet but the Gigabyte P34k v7 CF1 is lighter, thinner and has a better battery life than many of these while being more powerful than all of them (CPU and discrete GPU-wise).
This article is missing an entry for the Lenovo X260, which is arguably Lenovo's best business ultrabook. http://www.slant.co/topics/5508/~laptops-for-business has the X260 along with the T450s. Also depends on industry. Tech world definitely prefers Macbooks over Windows whereas traditional large corporations prefer Dells, HPs, and Lenovos.
I' m really wonder about most of the review about dell Latitude e5450 don't tell more about the I7 version. I bought it, cause of geforce 840m. I would glad to see a comparision between business pc model on their top version, not just a I5 against a I7.
1) Dependable, nothing worse than flying across oceans only to have your notebook fail. 2) have long battery life for travel or remote presentations 3) be simple to operate, 4) wide range of connection options, vga, usb, smartcard, lan, wlan as you never know what you might or might not encounter on the road. 5) light, you get tired very quickly lugging a 3kg+ monster around. 6) fast, try opening a 200mb powerpoint 7) accurate colour rendition, there is no point in displaying anything if the colours are inaccurate, it is totally misleading to you and your clients.
So all of these criteria can be applied to any notebook, your seemingly arbitary subjective selection criteria for these "top 10" Is baffling
Why isn't your top ultrabook here ? Why isnt your top light gaming computer here? Why isnt the latest Macbook Pro here ?
Why does you top "business" computer not even have a HDMI output?
Regarding security a "supposedly " important criteria in a "business" notebook..
I read nothing special or unique that sets their security apart from most other notebooks.
Your approach only perpetuates the status quo of branding and supports the manufacturers premium pricing models for notebooks that have nothing particularly unique to justify the pricing.
I got my first HP EliteBook 840 G1 with UWVA FHD IPS screen in April 2014 ( serial CNU409**** - manufactured on the 9th week of 2014) and realistically this is the only model (with UVWA screen) that should have been taken into consideration while choosing the 840 G1 for reviewing, hence I am not surprised that the 840 been ending up in the 4th/5th position if judged it by its pathetic TN screen.
