I also looked at the fabrixcases earlier this year. I was thinking of getting a fabrix case for my macbook, but I got an incase nylon sleeve plus instead.
I have the Sena Elega and it is quite tight. I got it at the Apple store with my 3G, knowing that is not really the case I wanted. I needed something to get me by so that I will not tear it up in my purse.
I just ordered a Beyza Slimline for 3G in Orange this evening with a coupon code that was posted by another member. Coupon Code is: WindowsMobile247. I have the purple for my V1, and I loved it. They do not have the purple for the 3G. Maybe they discontinued that color.
I think I will have my white 3G for a while. She needs lots of colorful cases.
