Let's say you want a 4G phone, because 4 is one more G than your current phone has. If you're deciding between Sprint's finest—the HTC Evo Shift and the Samsung Epic 4G—you're gonna want to watch this.

Both phones are sliders, both are on the same network, and by outward appearances seem pretty much identical. But! The Epic 4G, it turns out, is packing way more horses under the hood. As it should, considering it costs almost twice as much as the Shift.

There are a ton of considerations that go into buying a new phone, of course, and gaming/productivity performance are just a couple of them. Still, a helpful reminder that there's more to a phone than its name and its looks. [Wirefly]
