I think people are dismissing the battery charging issue because they don't want to see it.
So, let's add the TV Remote, Wireless computer mouse, Cordless home phone, And about 20 more items to the list of They Only Last 1 day.
tv remote lasts over a year
wireless apple mouse last around 6 months or more
cordless home phone? what the hell is a home phone? (i kid, but I haven't had a home phone for 15 years, thought everyone had got rid of them)
my point is, that your point isn't backed up very well. Even my MBA only has to be charged every few days, and my iPhone 6 could even go 2 days if I am not playing games on it to excess. While of course I wish my apple watch battery would last at least 2-3 days so that if I forget to charge it one night it doesn't die the next morning, but plugging it in at night isn't a big deal at all. if it really bothers you, pick up a stand that charges the phone and the watch and just set them both down at the end of the night.
the S6 has a wireless charging base and I am sure that Apple will give us wireless charging on the watch and the phone in the next 2-3 years. You have charged things for the last decade plus so a couple more years shouldn't be a deal breaker to buy something you will get enjoyment and utility out of every day
