I gave Drupal 7 a fair shot for a site I had to build quickly for my dad during the xmas holidays. I've a background in PHP and it was fairly easy to get shit up and running easily but then I gave up when I had to install tons of plugins to get image upload working. Supposedly they've integrated the file/image classes into the core for 7 but I didn't manage to get the stuff working fast enough, so I tried wordpress instead and although less powerful it at least could publish pages (wysiwyg) and handle image uploads without tons of configuration and plugins (and plugin dependencies).
I suppose that like for all open source projects documentation is lagging but it'd be a lot easier to adopt Drupal if the image stuff had just worked out of the box.
Now for the kicker: If at any point you don't want to keep your site running on drupalgardens.com -- perhaps because you feel the need to hack directly on the code, or because you really, truly need one of the 6,794 other Drupal modules that aren't yet supported on Gardens -- there is an "Export" option on the "My sites" page which you can use at any time to download the code, files, and database in a big tarball. Then you can install it on your local LAMP stack or upload it somewhere else.
I'll second this. Drupal Gardens is well worth checking out, especially if you are new to Drupal. You can get a site up and running _very_ quickly, the built in theme editor is amazing (think Firebug with a save button), and you really can get a tarball of the whole site with a couple of clicks.
I build Drupal based websites, but I'm not affiliated with Acquia.
