I still find the ACD such an impressive piece of technology. Almost 20 years after the first aluminium model was introduced, it's still relevant (well, the post-2004 ones at least), and they are still perfectly usable. Not something you could say about a lot of tech products from the time.
That being said, I'm currently home with no external display. Surprisingly enough, my current workload doesn't require a second display, and I don't have enough space for it anyway, so I don't miss it as much. Anyway, my current setup is just the Dell laptop and a tiny portable HP mouse, which makes me miss the other bits of my setup, especially the external HDD (not because I need extra space, but because of the content that's on it). Also, my room is a bit of a mess at home, hence no picture for this post.
That's an impressive amount of gear.
