A list of current and past hardware that I have worked and played with. I used to use Gdgt for maintaining this information, but that turned out to be painful.
NVIDIA GeForce GTX Titan (2013-)
The most powerful graphics card of all time. Roar!
NVIDIA GeForce GTX 590 (2013-)
Running CUDA and PhysX on this.
Creative Airwave (2013-)
Sounds tame and weak. But, perfect for home use for playing non-serious music or radio.
Creative WP-300 (2013-)
Sounds good and is very convenient to have around at home.
Nikon D5100 (2013-)
Does not autofocus correctly sometimes. Quite irritating.
Lenovo Thinkpad X201 (2013-)
Light and compact. Running Ubuntu on it.
Nook Color (2012-)
Running CyanogenMod 10.1 on it and using it to read Pocket and comics. Perfect for the job!
Dunu Trident (2012-)
Accurate, but also a bit tame to listen to.
Nokia C1-01 (2011-)
The cheapest Nokia cellphone I could buy. Menus are too slow to use and the audio is weak. Do not buy!
Sennheiser PX100-II (2011-)
I think this sounds the most enjoyable among all my headphones. A lot of the low frequency sounds also become audible with this.
Nikon D40 (2007-2013)
My first DSLR. Small, light, compact and shoots like a dream. Only reason I gave it away was the few focus points (only 3) and the not-so-high ISO.
NVIDIA GeForce GTX 580 (2011-2013)
Most of my successful PhD research was done on this beast.
NVIDIA GeForce 8800 GTX (2007-2009)
This used the G80 GPU and was the first GPU to support CUDA.
