If you are doing graphics work, consider a UXGA system (1600x1200 resolution) and max out the memory on the video adapter. If you don't, you will wish you did.
I am looking for a laptop that I can use for some graphic design & website design. I will be using this laptop for school as well as business. I don't really want an iBook. Many recommend IBM or Dell. What do you recommend for a person on a budget ($1800 or less)?
