What do people think about this bag? My SA showed me one today - just came in - and I really did like it. It's a great size, opens up completely like the Plume, but has multiple pockets inside, including a cell phone pocket. It was black epsom -- not my favorite leather, but it somehow didn't look "plasticky" like epsom can. I was supposed to have a Birkin coming in February, but it doesn't look as though it will get here......should I do the Sac instead??
