The Scholar's Workstation is located at the corner of University Avenue and Oxford Street in downtown Berkeley. They offer very good discounts on computers, accessories, and software for students and teachers.
You can order online or purchase items directly from their store, and individials not associated with a school can also shop there, you just wouldn't be able to get the discounted pricing.
I was able to get an iPod charger that was sold out all over the place online in 2 days from the Scholar's Workstation. Everywhere else had a 2 week waiting period. They promptly called me to let me know when it was in and I got a normally $25 item for $18 with my UC discount!
