If you're looking for WP hosting without the need to manage a server, we've been having a good experience with Synthesis' managed Wordpress hosting: http://websynthesis.com/
The only downside is that since their pricing is based on the number of domains/installs ($27 for a single domain/install), it'll get pricy for multiple small WP sites on a single account.
Yeah is a little pricey, but may be what OP was looking for.
The probably don't allow a WP network with multiple other sites CNAMEd to subdomains, which is how I'm set up. It's a little sticky to setup, but you have a free wordpress.org afterwards effectively, which is great for all my friend's and family's pet projects and mini sites.
