What I like most about the Flip Top is how well everything fits together.  Even the credit card slots work well.  Sliding cards in and out is much easier than with some other cases and doesn't make the Flip Top swell too much.  In the picture shown, I have all three credit card slots filled, yet the Flip Top hasn't increased in size that much.  I've been keeping the Smart Card that I use to logon at work in the case, which is great because I don't have to worry about losing the card or leaving it at home.  Visor -- don't leave home without it! 

The main concern with the Flip Top is that like all leather items, it has the potential to get scuffed, and more so since it is at your side.  I can see a few scratches on my Flip Top, oddly enough, on the back of the case.  They don't stand out, and the only reason I can see them is because my case is entirely brown leather --  a darker leather would probably hide scuff marks more easily.  Regardless, in a business environment, scuffing shouldn't be an issue anyway.  The only thing missing from the Flip Top is a pin hole for the Visor's microphone.  Looking at the case, I think that you should be able to manually insert a hole should it become necessary.  The price is higher than other beltclip cases, but the quality of the leather and the features of the Flip Top more than make up for this.
