I love Speedy. I have 2 of them. They're very classy and versatile. I can dress up or down with these two bags. They're pretty roomy, but I think the 25 one is a bit difficult to get in and out.
Before getting a Speedy, make sure that you can deal with hand-held bags. I personally love hand-helds, so they're perfect. However, some of my friends, who bought the bag because they thought they're pretty, ended up not using them. They're so used to shoulder bags, and hand-held is a real pain for them.
