A mouse. Just any mouse.
There are so many trackpad warriors out there (primarily Apple users) that complain they're being handicapped but they don't just go for the easy solution.
I've even seen some idiots stubbornly trying to do CAD work with a trackpad, and struggling in the process.
Well, Apple actually has good trackpad so I don't really feel handicapped with that. In some cases it's even better than mouse. Although if I had to do lot of CAD work I'd rather use mouse.
On PC however mouse is definitely better option. The PC trackpads I have used are either horrible or ok'ish. One PC trackpad I've used was a cheap mimic of Apple trackpad which made it much worse than an honest PC trackpad. If you try to copy Apple on budget it doesn't work. It just makes it a wish.com version of the better thing.
100% agree. I wouldn’t be caught dead using a mouse on my MacBook because macOS isn’t built for a mouse. But at the same time I won’t use windows trackpads and will bring a wireless mouse to avoid it.
CAD work is an outlier that would be always mouse, but that doesn’t mean everyone needs one
