Well, I'm a back-in-the-day Mac user. My last mac ran OS 8 when I got it, upgraded it to OS 9. It was a Power Computing Power Tower Pro (those oddball ones where Apple did license Mac OS on third party computers for a short while) Also had various performas, PowerMacs, etc.
But, I've returned. I'm quite happy to be back on the OSX platform. Just re-arranged my desk. I've got some serious cable management and cleanup work to do, but I've got it at a usable setup for now. Unfortunately, I also broke my office chair, and the 27" Cinema Display is waaaay up 'er. So my neck is straining looking up at a display from a chair stuck in the bottom position!
I have a homebuilt PC there too. I'm not MUCH of a gamer, but, I guess a little bit. I built it for gaming and also just, in general, a powerful platform. I do enjoy gaming now and again. Built it a couple years ago, specs are;
AMD Phenom II X4 965 BE @ 3.4GHz
4GB DDR3 RAM
500GB main HDD and a 1TB RAID 1 setup
ATi Radeon HD5870
You can see it in red in the bottom corner. It drives the 23" display on the right, and due to the 5xxx series incompatibility with the ACD, I'm waiting on an active adapter to adapt mini displayport to DVI-D. Then, it will drive both displays when I'm using it. You can see that white cable wrapped around the left side of the desk, that'll connect the ACD to the PC (it's a USB + Mini DP extension) so that I can easily switch from the MBP to the PC.
Then, of course, we have the MacBook Pro. When I bought it, I bought it along with 16GB of DDR3 RAM, and 2 Crucial M4 SSD's that I have setup in RAID 0. 8gbps read speed. Wonderful.
I also have a bit of a home theater setup in there, Pioneer head unit, sherwood speakers. Great for everything, LOVE listening to music on it. I don't currently have a way to attach the MBP to it, I'd like to find a USB sound card with optical out that'll work with the Mac.
Then, we've got the 27" Apple Cinema Display. That's not the thunderbolt display, you CAN still get the Cinema display, it's just kind of hidden in Apples website. I wanted the compatibility with my PC though and though some have gotten it to work, I think my chances are better with the ACD. Without USB 3.0, the thunderbolt display doesn't offer me much. At least, not enough to be worth not being able to use it on my PC as well.
Next up is an LG 23" display, works well. I use Air Display to feed the MBP over to that through Windows, works quite well. Could work better, but it's adequate. I would love to a find some sort of displayport or thunderbolt adapter that would somehow let me attach both displays to the MBP to run them straight off of this, but I doubt such a beast exists. Two thunderbolt displays would be great, but also very costly.
Also rocking the iPhone 4, getting the 5 in a couple weeks when my upgrade is up. The 4S nor the 5 were exciting enough for me to pay full price so I'll wait for my upgrade!
The little dude running on my desk is actually a USB hub I got... somewhere... don't recall where. It's attached to the ACD. There is another USB hub attached to the PC. There's also an enclosure for the MBP superdrive, which I used to install some software for the MBP, and will probably never use again, LOL. Finally, there is a Razer DeathAdder gaming mouse hidden on top of the Pioneer home theater unit. I pull that out when gaming as opposed to the Magic Mouse.
I've got kind of a love/hate thing going with the magic mouse. I just can't decide if I like it better than the Magic Trackpad or not. I don't like not having all the gestures, and it seems much less responsive to touch and less accurate with the gestures it does use, but I also am not thrilled about using only a trackpad all the time. I could, of course, just use a USB mouse like my Razer, but I love the gestures in OSX!
I'm inspired by some of your setups though. Using an elegant and quiet MacBook Pro I kind of feel like my desk should be a bit more elegant, LOL!
Oh, I also fired up Sheep Shaver on my MBP. Using OS9 on a Mac again just feels cool
