Macbook computer Technician

I got offered a job with a company called CSAT to repair Mac book laptops. Basically all I would be doing is diagnosing hardware issues and completing a repair. I have no opportunity in the near future to work on windows based computers. This will be my first IT position, but I am doubting how this will help me in the future. Would I be better off looking for Help Desk? I would think I would get more rounded experience working for someone like Geek Squad. Do desktop support technicians for companies even replace hardware in Macbooks? or do they send it off to some place like CSAT.

Some companies do have in house repair/upgrade facilities, so do use people with hardware skills. But in general, I'd say unless you want specifically a career in either Apple or hardware repair, the main benefits are having an "IT job" to fulfill experience requirements for a job you might want, and some "bonus" skills in Apple/hardware to put alongside your core skills (whatever those might end up being).
