Lilax,
I know you like the Vaja T-66, however I just wanted to give my opinion of the On & Off horizontal case I got from Factory Direct Cellular. This will help give you options for your future purchase.

I think this case is the best for business people who have to have their treos with them at all times. This complements well with business attires, as well as casual clothings. When using my treo, I prefer to hold it in its natural form. This case allows me to to securely carry my treo until the moment I need to use it. This case is all leather with firm spine. This case will not collapse and offer outstanding protection of your investment inside. In addition, there is a compartment where you are able to carry additional SC cards, as well as business cards.
Again, I don't want to sway you from your interest in the Vaja case, however I wanted to tell everyone what I thought of the On & Off horizontal case. Just my 2 cents.
Thank you.
