So where did it crack? Was it the screen or back of the device?
My suggestion is to get the most protective case you can possibly get to minimize the shock for future bumps and drops. It will give you the best chance to keep those cracks from becoming larger. If its the back of the device, try to cover the glass with tape or some kind of protective shield. If its the front, try to find a decent screen protector to minimize spider webbing.
I always hate to hear about someone's device getting accidental damage. These things aren't cheap.
On a side note: The cost of ownership extends beyond the retail price of the device. Budget in an insurance plan + deductible OR repair costs, accessories, etc. Doing so will allow you to enjoy your purchase even more knowing that it can be fixed/replaced if broken.
Edit: You did say SCREEN. I don't know why I missed that. Regardless....good luck!
