I’m wondering how many of you Growl ($1.99 in the AppStore) fans out there, and if you’re using a Mac you most certainly should be one, are using HardwareGrowler. If you’re not, you certainly ought to give it a look.
For those of you not familiar with Growl, it’s a very nice notification system for Mac OS X. In a nutshell, it allows applications to send you notifications. HardwareGrowler lets you know when devices are connected or disconnected from your computer. This includes FireWire, USB, Bluetooth, FileSystem Volumes, and Network Interfaces.
