In current use:

• Canon EOS 5D mark II
• Canon EF 17-40mm f/4 L USM
• Canon EF 50mm f/1.4
• Sigma 70-200mm F2.8 EX DG APOMacro HSM II
• Canon Speedlite 430EX II + Sto-Fen Omni-Bounce EW
• Velbon Sherpa 250 tripod

Semi-retired, from my early days:

• Canon EOS 450D
• Canon EF 50mm f/1.8 II with a 55mm UV filter – currently broken. Works decently stopped down to around f/8 and below, but anything higher and it becomes too soft (I might have dropped it – the barrel came out…)
• Canon EF-S 18-55 f/3.5-5.6 IS -replaced by the 17-40 f/4L above
• Tamron 70-300mm f/4-5.6

Computer:

• 27″ iMac (3.06GHz Core 2 Duo, 4GB RAM, 1TB HDD) – although I’ve had very minor screen flickering problems, these are rare and easily fixed. It’s amazing for photos – nice big screen, powerful enough not to break into a sweat even when rendering 1:1 previews for several hundred photos at once.
• MacBook Air (1.6GHz C2D, 2GB RAM, 80GB HDD) – not a recommendation! I won it, and it serves me fairly well, but the tiny, slow hard drive is simply not good enough for even my fairly light usage. Get a real MacBook at the very least instead. It serves fairly well for an on-the-go machine, but it’s not for every day use.
• Adobe Photoshop Lightroom 2.2 (although using the Lightroom 3 beta 2 is fantastic)
