Meh.
Article is kind of silly IMO, at best only semi-mustician since it's advocating spending a ridiculously large amount on a purpose made product - yeah, I know...supposed to be snarky and poking fun at the consumer sukka's, but still........
1) "Saves money". False choice. Assumes only alternative is to constantly buy pre-bottled water. It's called a fountain. Or, see below for an even more economical choice than spending large amounts on purpose manufactured bottles.
2) "I don't have to dispose of it every time I empty it". WTF?!?!?! Are you a dense, consumer sukka? Why is it again that you have to toss a perfectly good water bottle that you bought for a buck-twenty-nice, that comes free with a liter of water, soda or sports beverage? Hello....McFly.....you can reuse a plastic bottle - peel label, refill from any convenient source (in my case, usually mountain creeks or springs).
3) "Convenience" / "Sturdy" - Yeah, but you don't need to spend $29 to get that....the same buck-twenty-nine bottles I use have been in use for....mmmm.....about 5-7 years each. Nice thing about them - no dents when ya drop them. Squeeze the air out of the empty ones and put the cap back on when you need more volume in the pack. Clear plastic lets you see when there is "funk" on the inside so you can rinse with hot, soapy bleach water.
The funny thing about reusing sports drink, soda or pre-filled water bottles over as ones "water bottle" is that long distance hikers have figured this out 15+ years ago. When hiking through the desert, you need greater capacity since the springs / creeks are further apart. Buy 1-3 additional bottles that come pre-filled with a free liter of sports drink, soda or municipal water- total cost, a few dollars. Once through the desert and the extra capacity is no longer needed, leave empty bottles in the last hotel you stayed at.
Note - there is only once circumstance where I'd advocate for a purpose made water "bottle". That would be backpacking in wet conditions where hypothermia is a possibility. Filling a 1 liter Nalgene type bottle (or equivalent) with boiling hot water makes a nice impromptu hot water bottle (soda bottles melt at this temp). Put inside a sock, take with you inside of sleeping bag or tuck inside of the jacket - metal or insulated purpose made bottles are either less suitable or unsuitable for this purpose (too rapid or too slow heat transfer, respectively).
