My Setup

Com­puter

Dell Dimen­sion 9200 (Win­dows Vista)
Main desktop. I use it for all my web dev.

Gen­eral

Logit­ech G15 Keyboard
Prob­ably the best key­board there is. It has a screen, back­lit keys and mul­ti­me­dia con­trols that don’t feel clunky and out of place. It’s great to type on and, provided you can find one in stock, they’re not ridicu­lously expensive.
Logit­ech G9 Mouse
Again, a fant­astic product! It fits per­fectly in your palm and feels solid. Cer­tainly not for left-handed people though.
Dell 22″ Widescreen Monitor
First off, your next mon­itor should be a widescreen if it’s not already. Secondly, it should be big. Once you get past 22 inches, though, sizes are sparse and usu­ally carry high prices.

Web Devel­op­ment

Aptana Stu­dio
I used to use Dream­weaver but I found it unne­ces­sar­ily bloated and con­sequently slow. Aptana is a bit more agile and the Com­munity Edi­tion is free.
Adobe Fire­works CS4
Much easier to use than Pho­toshop just not as powerful.
Adobe Pho­toshop CS4
The lead­ing image editor.
Moz­illa Fire­fox 3
This is very eas­ily my favour­ite browser. It’s com­plete with the Web Developer tool­bar and Fire­bug, among others.
Vir­tu­al­Box
It’s free so it’s a lot cheaper than buy­ing another com­puter and a lot safer than dual-booting. In short, I can test a vari­ety of dif­fer­ent oper­at­ing sys­tems quickly to ensure pro­jects work as they should. I find it lighter than VMWare and a little bit easier to use as well.

Music

Cre­at­ive X-Fi XtremeMusic Sound Card
Good sound card.
Cre­at­ive Inspire T7900 7.1 Speakers
There’s noth­ing like being immersed in sound. There are 7 of these speak­ers and a huge sub­woofer. When joined with a Cre­at­ive X-Fi sound card, the res­ults are phenomenal.
iTunes
iTunes is love/hate soft­ware — many people hate it but I quite like it. Sure, it doesn’t have codec sup­port for any­thing out­side Apple con­fines — FLAC sup­port, for example, is some­thing I wouldn’t mind. But it does, how­ever, sup­port the iPod per­fectly and as I have two iPods, that’s a huge advant­age. It’s not a bad look­ing piece of soft­ware either, com­pared to Win­dows Media Player.
iPod Video 5G
Gran­ted, it was expens­ive and video play­back drained the bat­tery but I love it and it has all my music in one port­able device.
iPod Shuffle 1G
For a light jour­ney, noth­ing beats a Shuffle, in terms of port­ab­il­ity and simplicity.

Port­ab­il­ity

LaCiE 500GB External Drive
Writ­ten on the side it says “Designed by F A Porsche”. It’s a great hard drive although it can get fairly warm after a while.

Mis­cel­laneous

Sony Eric­sson W200i
A great phone at a bar­gain price. It’s a Sony Eric­sson so music play­back is great but there has to things said about the lack of Bluetooth (it has Infrared instead) and the poor cam­era. At £25 ($50), why complain?
