It would mean spending time configuring a server, which I have no interest in doing. I know nothing about Linux, and haven't dealt with any server configuration in over a decade.

The minimum number of things I have to deal with the happier I am - I want to get some functionality out there, and being able to just code it, upload it, and then let Google worry about databases, backups, upgrades, etc. makes life staggeringly simpler for me.
