you watch can join wi-fi networks, so for places like the gym or work where you might be frequently and not want to carry your phone, it lessens the need for cellular.
a couple things.
--you can't enter a password on the watch, so you must have joined it from the phone at some point.
--you can't pick a network from a list, so even for a place with no wifi password, you must have joined on your phone
--You can't join a network that has a log in page, like you might see in a hotel. even if you've joined from your phone
--the watch keeps all the wifi passwords that are in your phone
keep in mind your budget, and that the watch is probably a 2-3 year life span,
as they're fairly new, year over year improvement is pretty big, so a watch that's a couple years old will feel very slow.
It's not a normal "investment" purchase like a nice watch, it's actually quite the opposite.
you can get bands on amazon, i'm not a "dressy" person, but i do have a $15 milanese loop that works for when i need it.
also have a black leather band also $10-15 bucks.
think about color pairings
to me, a black watch with silver band looks off, but a silver watch with black band looks ok,
as far as easier to remove from your wrist, it's the same as a normal watch,
if you have dexterity issues, both sport band types are fairly easy, just have to push the nub through the hole on one, and the other is like a Milanese loop, but nylon and velcro instead of metal and magnets.
you should be able to try any combination at the apple store. they have a large selection you can try on.
and 100% no questions asked, get the apple care+
