Computer buyng

i advice you to bay a laptop because you can take it with you any time any place .You must choose a powerfull laptop and not very expensive

Configuration for system depends upon what kind of applications are going to be used. e.g. if you are going to use it for high end graphics applications like games CAD software etc. then Graphics Card is recommended. Choice of laptop or desktop again depends upon your need, if you are frequent traveler or likely to shift your places frequently, then laptop can be a good option.

in that case go for a pc and not for a laptop because they are dear and you should buy a new one and don't try a used one.if you buy a laptop then i will say buy a toshiba, i am using one and it is the best ask for a dell 3 ghz processor,1 gb ram pc. i recently bought one and i found it fairly fast and it is not that dear. hope that helps.

Well it depends on what you would be doing, if you are just going to keep it at home then use a PC but if you would be constantly traveling and using it then a laptop would be much better, check out the computers dell have on sale, they are really good and you can get a great computer for a great price with dell :)
