IMO, if AM does "his thing" and we get taken out, it will be for a multiple of your suggested $3-5 bil. Landing a deal with Apple alone could generate 100's of $Millions in Revenue (ie. 40M iphones at $10/phone, say 20% profit for 228M fully diluted shares is 0.35/share at a P/E of 60 is $21/share or a value of $4.8B)
And that is just one customer!
Yes, this is just a (lofty) illustration, but is it a possibility??
