The iPad is a great device for checking recipes while cooking in the kitchen, but few of us are willing to keep it close to the action lest it become tainted with meat juices and other bits of food shrapnel. One solution would be to pick up some of these disposable, waterproof Chef Sleeves.
Just slip one over your iPad and secure the resealable sticky strip to enjoy the peace of mind that comes from knowing that your precious tablet will be protected from spills. The sleeves are also thin enough that you can use the touchscreen through the material. The box even doubles as an iPad dock.
The problem is that they cost $20 for a box of 25, so you might be better off reusing Ziploc bags and other, similar resealable pouches.
