Really disappointing that they didn't make this easier for users. Not off to a good start with an OS that is in bad need of good publicity. I got 8.1 on my laptop this morning, and I like the changes that were made, but man am I annoyed that they're making me re-download it on each machine at home that I want to upgrade.
not really sure how much easier they can make it.
Open Store, Click on item, Click install. Wait. profit.
as far as making it more accessable to people that would like to download the update and do it later, not so much, but as far as easier its VERY simple.
