What is the difference between パソコン vs コンピューター?
Generally, what Faily Feely said in comment is all:
パソコン is thought to be an abbreviation for パーソナルコンピューター (personal computer).
When used as パソコン, I'd imagine a (home) desktop PC.
When used as コンピューター, its meaning is generally the same as English computer, I suppose.
