Build Your Own LEGO CD Case

I thought it was odd when I saw "incandescent light bulb" on the list. Yep, the list is from October 21, 2013 - just before the phase-out really took place.

Solid state is a relatively new technology and still isn't as cheap as an optical drive, about 4x more expensive for the same storage space. That's why it hasn't completely taken off. It will probably replace optical drives eventually, which have surprisingly been around since about the dawn of computers.

Magnetic strip on your credit card? I would definitely say that tech is obsolete. My card has a magnetic strip and a chip and a tap option but I don't think I've ever used the magnetic strip. Tap is most common in Canada.

1) the alkaline battery is still less hazardous (it's not even listed as hazardous) than most other battery types we use. Lithium is certainly not better.

2) the DVD is outdated indeed, but the optical drive numbers should at least be from bluray. (Still slower, but much cheaper to produce than solid state cards.) Both should be outdated because we download or stream everything these days.
