Hi Ladies, I'm thinking of buying an oversize Muse, but because I telecommute a lot, it would need to fit my laptop, its a standard size 15 inch. Do you ladies think the OS Muse would fit my laptop and would the straps hold up to the added weight over time? Also since the laptop would be a little heavy do you think it would make the bag droop while I carried it? I noticed a lot of you can carry it on your shoulder and that is a plus, please let me know your thoughts. TIA!
