most people in this forum would agree that you will eventually succumb to evil things.
IIRC, myshadow is a girl and much less likely to succumb to evil things on the internet[if you understand what I mean]. Also, a desktop can be in a private place too (like a bedroom or whatnot).
There are many good reasons to get a laptop – including needing portability for school. I assume myshadow is in that age bracket.
Myshadow – do you need the laptop just for typing up reports and stuff? Surfing the web? If so, you don’t need anything fancy at all. You can probably get a laptop for around $500 then. Although, for the same price, a desktop gives you much more value.
