I still haven't decided, I haven't had the chance to look at the siena yet. I once bought a speedy b 30 and I returned it. It looked too big on me, I felt that it was a luggage bag and comparing it to the speedy b25, the speedy b25 wasn't confortable because of the zipper and I thought it looked too small hand held. When I saw the siena online I felt this might be the bag I want as it has the same features of the speedy, it looks more feminine and the opening seems bigger and that makes it more practical . It is also bigger than the speedyb25 except for the depth which I think would make it look better handheld. I have high hopes towards this bag and most probably I would go next week to the store to try it on and may be buy it.
