You have to learn to use it as you had to learn to use an ordinary mouse or trackpad. Once you are comfortable with it a trackpoint is 10 times better than using a trackpad (probably even more ;) ). For example, you don't have to leave your hand(s) from the keyboard or awkwardly balancing the labtop on your knees when moving the cursor.
Nope, the trackpoint is simply inferior, especially for scrolling.
Nope, you have no clue :) thats what a trackpad is good for. The trackpad is easily reachable with your thumb without leaving your fingers too much from the keyboard (most linux distros have the right of the trackpad configured as scroll area). So no annoying multi finger scrolling needed.
Furthermore, middle mouse button + trackpoint scrolls as well, so scrolling really isn't an issue.
No sarcasm here. It took me about two weeks to adjust to the movement/speed curve of the TrackPoint. It then took me another two months to reach sufficient proficiency to bypass a mouse and trackpad. I am sure some folks could adapt faster, but I had to surpass 22 years of mouse muscle memory.
My job entails writing emails most of the day, Salesforce, and internal communication tools. I love not having to take my hands of home row. I haven't been able to quantify any speed improvement. But, I feel more focused and in the "zone" more often. Could all be my imagination. It could also be that I find ThinkPad keyboard wonderful to use too.
I do use the Adobe CC Suite for the occasional video, presentation, or mock up. No issue using the trackpoint there either.
Are you expressing sarcasm here? Using the nub mouse is an infuriatingly frustrating exercise in trying to navigate the cursor to a point on the screen with some semblance of speed, and without overshoot. It's minimally five times slower than using a mouse.
