Simple, yet cool and nice:
A MBP, preferrably 15" and a BT Mighty Mouse. 15" to not make it look too big, and the 17" not as portable for school as the 15". On a small wooden desk, either natural wooden color, or white as the tables in Apple stores. You have very few wires. If you can, avoid external speakers, get some good quality Sennheiser headphones if needed. MBP speakers are great BTW. If possible, have just the MagSafe cord running out from the MBP. Get a nice modern lamp, preferrably with some brushed glass as cover, and brushed steel for the stand. The lamp is just to make it look nice, the MBP has backlit KB and an extremely bright screen (get a glossy one). Don't get a mousemat. Though it makes a sound while the mouse moves over the table, it looks so much nicer/cleaner. A nice black chair, not too big and focused and comfort, yet more to fit in with the cleaniness of the excisting setup. Remove any papertrays, tools or other objects from the desk. It's just you, your MBP, your mouse, and possibly a lamp for decoration, not for lighting.
Advanced, yet cool and nice:
Pretty much the same as above, except a few changes. The desk must be very large. There must be much space leftover. You need a 23" ACD, and a Apple BT KB, NO iCurve FFS!
No iCurve! The MBP is on the left side of the ACD, with mouse and KB directly in front of the ACD, at a comfortable distance to the display. The MBP is used for iTunes and windows not in use. ACD used for main tasks. The MBP placed at a slightly crooked angle, whatever you prefer. The chair must be a bit beefier and comfier, yet not too big, it must not steal the Apple products thunder. You place
these speakers a the ACD, with the subwofer UNDER the table, gives better sound, and look better. You still try to hide cables and any other objets that may smudge the cleaniness of the setup. You may wanna wire them to the desk.
iGary has this way with cables and wired, he's very good at it. Perhaps you should PM him and ask him for advice.
This is IMO the two perfect MBP setups.
