Fairfax strikes $4.7-billion deal to buy BlackBerry
Fairfax Financial is run by Prem Watsa, a cautious, methodical, "value" investor who has compounded Fairfax's book value by nearly 23%/year over the past 27 years.[1]  (Fairfax's stock price has gained 19%/year over the same three-decade period.) His approach and track record are similar to those of Warren Buffett earlier in his career -- i.e., not someone one should normally bet against.If Fairfax is offering to pay $4.7 billion to acquire RIM, Mr. Watsa somehow must have convinced himself that the value of RIM's business exceeds $4.7 billion by a large margin.However, to me Blackberry looks like a dying platform suffering from anti-network effects (that is, fewer and fewer people use it, so fewer and fewer people want or need to use it). I don't understand how he gets comfortable with that number.--[1] See page 8 of Fairfax's last annual letter to shareholders: http://www.fairfax.ca/files/Letter%20to%20Shareholders%20fro...
