Touchpads have one great advantage: no clicks.
Clicks = bad.
No clicks = good.
But if you replace the clicking with something even worse then it doesn't work out.
I'm using the bamboo pen and touch, gicantic surface, very accurate, and when you want extra precision you can use the pen. It pwns even for things it's not intended for, such as browsing.
But there are downsides. Apart from most people here not liking it, Ergonomics research has found that the constant tension to keep all fingers but one away from the touchpad is not good long-term. I can see why.
I have never used the device you are using but I used a touchpad thingy on a laptop for a couple of minutes and it burnt my fingers quite badly so I never used one again.
With my horrible hand pain condition anything that would cause a regular person damage from doing for a whole year continuously, causes me intense pain in 5 minutes or less.
Like the "keeping your fingers under tension" thing you are talking about.
I cannot EVER keep my fingers under tension ever anymore. If I do so for any reason then my pain escalates in 5 mins or less and I am destroyed for the rest of the day. So I always always always keep relaxing my fingers. Use them when needed, then relax.
Back when I was healthy I would code all day or game all day and keep tension on my mouse fingers and hand continuously all day long. If I was playing a game and the game lasted 8 hours then that was 8
continuous hours of tension on my tendons in both hands but especially in my mouse hand and arm. Totally crazy. I now realize that doing that over and over again is horrifically unhealthy.
One should avoid keeping the tendons and muscles under continuous long-term repeated sessions of tension.
