jd - the biggest challenge of devstack (for me!) that it works as you would create multi sites. So it does not use the site/default folder but creates a sites/[domain name] folder. Files stored in this new folder too. I mostly use sites/default on live servers, so I have to synchronise the files.

On the other hand it is much more confortable to use devstack than MAMP and quicker to create/import a site
