With the HTC One (M8) for Windows graduating from a Verizon exclusive to being available on AT&T and coming soon to T-Mobile, we've been reviewing some cases to give you a taste of what's out there.

Next up is the StoryLeather Side Flip Stand case for the HTC One (M8) for Windows. It is a premium leather case that acts as both a stand and mini portfolio for your smartphone.

First and foremost, the StoryLeather case is very high quality. The outside leather cover is textured with a pebble surface to give it a look and feel of a professional portfolio. Two magnetic tabs come together on the open side of the case to form a clasp to keep it shut. Opening it is as simple as flipping it with your thumb.

The leather cover has cutouts for the HTC One's speakers, rear cameras and flash, while protecting the front-facing camera.

Inside you'll find a suede lining that helps keep the HTC One's screen free of dust and lint. The inside of the flap also smartly includes a well-crafted pocket for holding a credit card, money, or business cards. Opposite the front flap is a hard shell that the HTC One (M8) snaps into. This shell holds the phone in place and protects it from the impact of drops.

In hand, the StoryLeather case feels good. The textured leather makes it comfortable to hold. Like just about any flip case, this one is a bit awkward to hold when the cover is flipped back to make a phone call. However, it is still better to hold than its brethren, like the HTC Flip Case.

In addition to acting a tiny business portfolio, the StoryLeather Side Flip Stand case also doubles as a stand. When placed with the front flap down, the hard shell slides forward to stand the phone up in landscape mode.

StoryLeather has crafted a top-notch case for the HTC One (M8). It just as easily feels at home in a business meeting or a nice restaurant. It's so nice, in fact, that I feel odd using it while wearing my usual cargo shorts and band T-shirt. But if you're more of a suit and tie or business casual, kind of person, the StoryLeather Side Flip Stand Case will serve you well.

The StoryLeather Side Flip case is available in the Windows Central Store for $49.95.
