A little more info on my Pi setup, perhaps it will be useful to someone:
I use a 120 gig usb SSD instead of the microSD card.
The sd cards will eventually "wear out" with multiple r/w operations (they claim, I haven't had it happen. Yet.).
The SSD should have a longer lifespan than a microSD card. Faster, too, and the same size as a Pi.
When adding almost anything to a Pi via usb, you're going to exceed the limits of the power supply*, so a powered hub is a good idea. Keyboard, mouse, SSD, thumbdrives, camera, and other usb stuff you need can plug in there, instead of into the Pi usb ports.
*note: this is not exactly true. The power supply may be 2 or 3 amps, but it feeds the Pi via a micro-usb connector. Which, if I'm not mistaken, was designed to carry half an amp max. Therefore, your average usb to micro usb cables aren't designed to handle more than .5 amp. Thin wires = voltage drop. You may have to try several different cables before you find one heavy enough to supply full voltage, and get that pesky "low voltage" warning to go away.
