I'm struggling to keep up with this every day- it really is hard to carve 5 minutes out for it.
15. Ubiquitous cellular connection
Weak but it's true. I have no idea how I managed to see my friends before we could connect via cell phone. Although, for me, pre-cell phone days were college and high school, so I saw my friends around in person far more often.
I can buy pretty much anything, anytime. For someone with slightly esoteric hobbies (electronics still doesn't have enough clout to get really great local stores), that's a must.
