If you're going to buy a computer anyway, why not a laptop?
Working on a laptop, you have three choices.
- You can have your head bent over to look at the screen, which is terrible for your neck
- You can have your laptop on a stand and type with your hands way up instead of the natural position you should type in
- You can buy an external monitor or keyboard to correct these issues
That's just one reason not to buy a laptop if you don't need it. The cost difference is another big one that others have already addressed here.
