So, I have a 2 week old Macbook and add 4 kids (ages 3 mths-7 years) to the mix = potential trouble. I want to protect it as much as possible. What would you suggest or advise against? I've looked on eBay for the snap on plastic cases, keyboard (full or half) covers and screen protectors. Are they all worth it? Are some really garbage, and others not? Which ones would (have) you buy? ANY suggestions would be great. Money is an issue though - so the lowest price the better. THANKS for all the potential help!
