I don't need a holster, but I've been in search of the perfect case as well. I had an ok leather one with a flap, but it also had a clear plastic cover over the qwerty keys, which made it difficult to type. Between the annoying plastic thing and the bulk, in the end, I couldn't take it anymore. The search continued.

I recently got one of the Seidio extended battery cases, and I think I found the perfect case. I love love love it. It protects the phone, but it is very light, and doesn't feel bulky at all.

For a purse, I found a nice Baggallini bag that has a small zipper pocket that this phone fits in perfectly. The bag is light, and the strap is long so you can wear it over your shoulder if you want. Link is here: http://www.ebags.com/baggallini/bon_...modelid=107671. I got it at a closeout sale in a store, so the price I got was a lot cheaper than the one on this site. But it's a quality bag, so I don't think this price is out of line.

Good luck...
