For those who own or looked at one.... is this bag worth buying? It looks great on person but it is quite trendy so im not sure if it is worth purchasing in terms of practicality? Will it be something that will be alright to carry for years to come? Also, it was pretty heavy, does this become a problem later on? (its hard to tell when just trying it on at a store) Lastly, is it easy to get in and out of? Thanks for any input/advice. Here is a pic I found on eBay of it.
