I think it's a case of the tyranny of minor differences and what people are used to. My personal phone is an android and I'm used to it and like it, while my work phone is an iPhone and I use it for entirely different work-related reasons that it's great for.
Never shall the two meet! I actually like having my work and private lives segregated into two separate OS's that have little if any overlap.
Also Columbia owns brands like Prana and Mountain Hardware, so if you want higher quality stuff that's still basically Columbia, you have plenty of options.
The same is true of many other companies.
