what's more convenient to use?

I think it would depend on a few different factors for example, what its used for, how long a person is on it, etc etc....For me I like my PC but am looking to get a cheap laptop strictly for writing purposes so I can take it around with me, write in bed, write when I'm outside etc etc....Obviously ppl who are at school or use a computer a great deal for work etc having a laptop I would think would be more logical..
