EVO Mash Up
 
SwiFTP is a pretty cool little free app that essentially allows you to host an FTP server on your Evo.  While obviously this isn't a good method for public file sharing, it is a pretty handy way to move files to and from your phone wirelessly.  Set up of the application couldn't be simpler.  Just download the app and install it.  Once you launch it, the settings screen will come up where you create a username and password to be used for access to the FTP server.  You can also specify what the root directory should be.  Lastly, you can elect to just enable the server over the WiFi, or optionally, you can enable access to it via a proxy server over 3G/4G.  Currently, you must use the developers proxy, but hopefully they will enable you to specify your own at some point in the future.

Aside from the fact that you will use a decent amount of battery while connected to the server, the only other limitation I noticed is that the password must be numeric.  Not really sure why that is.

There's a visual guide for configuring the app, including how to map to it from within Windows over at Addictive Tips.
 
I don't own a SlingBox, and to be honest, haven't really found a pressing need for one.  However, it is a pretty cool concept.  Fortunately, they've released a version of the SlingBox mobile player application for Android now.  The folks over at Engadet wrote up a decent review of the app, and it appears that overall, they like it.  Read the full review here.

One of the things I find a little aggravating on the EVO is that the power button on the top of the phone is sort of difficult to press without looking, especially for those of us with fat fingers.  That being said,No Lock is a free app that helps resolve that problem in a somewhat round-about way.
