Today I'd like to show you a photo of my workplace in the Applied Informatics office. In clockwise direction: OKI C5600n color laser printer, Sony Vaio notebook, Apple PowerBook G4 and 20" Cinema Display, external hard disk, Dell 20" display, IBM ThinkPad (behind chair), two ARM-9 development boards, Apple Mac Pro and 20" Cinema Display. The photo has been taken with my cell phone camera, so the quality sucks.
And yes, occasionally I use all of these computers at the same time. Especially when it's release time.
