As a Basecamp user, I couldn't agree more! Basecamp is such a useful tool, but it does scream for a mobile app. There's an upcoming app called Outpost, that looks promising http://outpostapp.com/ . Unfortunately I'm in the Blackberry camp, so hopefully there will be a Twitterberry-like solution! Fingers crossed... Great post! - CJ Guest from FriendFeed MT Plugin

Jason, thanks for the list of third party products, we will check those out! I'm a bit confused by this statement tho: "You don't need to log into Basecamp to reply to a comment on a message, to-do, or milestone - you can just respond via email. Just reply to the message/comment in your email client." RM: you can indeed just respond by email, but that doesn't get saved into BC (unless I'm missing something). So essentially the conversation shifts out of BC and into email, which kind of defeats the purpose of a project mgmt system IMHO. If there was a way to reply by email and save the message to BC, that of course would be great. - Richard from FriendFeed MT Plugin
