EMP makes for a great story line in a movie or conspiracy theory, but the fact of the matter is, EMP is grossly overrated and not really anything to fear.
1.) EMP would not wipe out ANY critical data. Critical data is not sitting on servers in your moms basement. It is backed up on multiple servers around the country, and around the world. The server rooms this data is protected in are built to protect against EMP. Critical data is also backed up onto solid state media that is not effected by EMP.
2.) The effects of EMP have been grossly exaggerated by hollywood and conspiracy theorists. The military does EMP testing on White Sands missile range in New Mexico all the time. They have found that EMP is just not that effective. Most vehicles will still operate after an EMP. Communication backbones around the world are made out of fiber optics. While the switches on the ends of those little strands of glass can be effected, the actual network is safe. Like critical data, critical switches on the worlds communication backbones are stored in rooms designed to protect against EMP. Moreover, spares for those switches are kept on hand, and also protected against EMP.
3.) The power grid will more than likely be wiped out by an EMP. Not because of actual damage to the infrastructure, but due to the loss of computer operations and safety systems at power plants. While the loss of power would suck, the grid could be restored in under 90 days.
So basically, worse case scenario from an EMP would be civil unrest for short term of time caused by the lack of communication and power. Oh yeah, and people wouldn't get to see "American Idol." Not exactly an end of the world as we know it type of event, and precious metals and ammunition will both be handy to have.
This is something to discuss, not gold/silver vs ammo - history has already answered that arguement repeatedly (and history always repeats itself). The EMP power-grid statement in #3 - I don't agree that it would be back up in 90 days. If most of the replacement parts are fried in the burst (which is likely because large transformers and circuitry aren't stored in huge Faraday boxes) and the factories that make those parts need electricity - it would be 6mos - year at least. Under normal circumstances there is usually 6mo lead times on major parts for power companies, let alone in a situation like we are discussing. Albeit fictional, this book is a very good read on this subject: http://www.amazon.com/Lights-Out-David-Crawford/dp/0615427359
