#14 I had that Tivo remote with the headphone jack. Takes 2 AA batteries, has no charge jack, batteries always dead.

#14 I still have that Roku remote and yes, batteries go super fast if you use it for headphones. Fun idea, but buy your AAs in bulk.

#13.... That will be much used with that tread pattern if you have the patience.
Bottom line is a tread like that plain sucks, unless only worn indoors

Uh....rechargeable batteries?

#15 is a bad idea. little kid tries to enter and adult on the way out brains him with the door.

#19 Reading a map before you set off. What a novel idea

Yup, plus #21 In carriages on the London Underground there's maps of the whole system and that line's stations are shown in order (with any interchanges) so you don't have to keep looking at your phone to be ready to get off at the right stop.

#22 It's such a good idea, it's spreading fast. They have it on [insert other metro system] too. And on #23, #24, #25...

Wow
