Only Microsoft tops them in the totally self-inflicted wound stakes
The 21st centuries mobile losers, in order of asshattery:
1. Microsoft. Imploded because it was too smug to think it could fail.
2. Blackberry: Sat on its corporate laurels for too long.
3. Nokia: Had the chance to go next-gen with Android which would have saved it, but instead believed Microsofts burning platform bullshit. About to fix that now it's free of the beasts evil clutches, which is still a big gamble but pretty much their only hope.
