Well... if you want performance and space and good service, get a Lenovo IBM. Flipside is that you'll look like an accountant. I have one, love it, god damn ugly computer though.
Other PCs that are great are Acers. God damn good laptops. Space, looks, power, reliable.
Dells are okay, but the aftersale service is not good at all.
My next laptop is a Macbook, and this comes from a person who hates Apple, but cannot stand PCs anymore.
