ITT: Vault pretends he knows about computers.
I don't know about you, but I rely on my laptop's portability CONSTANTLY. It's not only nice to be able to take my laptop wherever in the house, but most of my relatives do not own a useable computer.
I recommend a laptop over a desktop, but it's really situational. Desktops are cheaper, but I'd much rather pay ~300 more dollars so I can use my computer whenever I want to.
I use 4g of RAM and I recommend you do so as well.
In my personal experiences with the family PC, an HP, the computer is extremely problematic and HP's customer service is awful. Every time we sent it in for maintenance they formatted the hard drive. if that happened to my personal computer I'd kill myself. I have so much junk on here.
I use a mac, and you can buy a macbook for 1000 bucks.
Are your parents willing to chip in some money, too?
