I'm considering getting an M4 MPB. But when I close one and pick it up in the store with one hand—my customary way of handling laptops while commuting/traveling—I'm concerned about it slipping through my fingers and crashing on the floor, given its weight, thickness, and slipperiness. An easily occurring and potentially expensive accident. Seems like a pair of thin but highly grippy rubber strips (maybe 4x16 cm), held on by a strong adhesive and placed along the top & bottom front edges, would make unbagging and bagging this beast safer. A DIY solution from a well-stocked hardware store would be easy enough. And I know some users would consider this desecration. Are there such after-sales products? Long-time users: Am I making too big a deal about this risk?
