Wheeled Laptop Bags / Mobile Office Bags / Trolly Laptop Bags
Laptops in themselves are not overly heavy but it is natural to include your other bits and bobs in the same bag and then..."I better take my power supply too!". The ultimate payload on your shoulder can be enough over time to skew your frame. You can end up with one shoulder lower and further back than the other one - not surprising that this can cause pain and be a factor in RSI. A better solution is to get a Wheeled Laptop Bag. It doesn't have to be tartan and accompany you to the shops! They generally look very business-like and once you start using them you will quickly feel the benefit.
