Ok gals: I have a huge debate going on in my head as to whether I should keep the Tivoli GM (brand new, just purchased), or if I should return and get the Tivoli PM (just arrived into the store, on charge-hold). Part of the debate in my head is whether the GM is too big/PM is too small. I am 5'5" w/o heels, 5'8" on a given day w/heels, 130 lbs. Another part is if/when I am tired of this bag, which one has better re-saleability on eBay? Last but not least - at times I love bags that can be worn on the shoulders if I am running lots of errands. But I wonder if the GM is too bulky/big to be worn on the shoulders (like the Damier Berkeley bag)? And whether the shoulder straps will easily slip off the shoulders. The PM can not be worn on shoulders though wearing on crook of arm/handheld is fine for the most part. ADDENDUM: Another factor to include, that is making my decision tough is that the Tivoli GM was purchased pre-price increase, tax-free. The Tivoli PM will be post-price increase, taxed. So the price difference between the 2 is about $200.
