It's been a busy week for BlackBerry (BB 3.21%), which released preliminary earnings estimates a week ago only to announce a possible $9-per-share buyout deal just days later. The company has now announced its official figures, and investors were relieved that the results weren't at the low end of guidance.

Two important data points remain unknown, though. BlackBerry didn't share any information regarding its current subscriber base, nor did it provide additional breakdowns of its product mix. Investors want to know how many BlackBerry 10 units were sold, but the company cancelled its conference call in wake of the Fairfax offer.

The market is clearly skeptical about the deal, since shares are trading at a substantial discount relative to the offer price. Fairfax can still walk away, or it could fail to secure financing, among other possible risks. Should Prem Watsa stay away from tech?
