CNET's review team did a prizefight review of the Samsung Blackjack vs the RIM Blackberry 8800...

As a spoiler - the Blackjack won!

To quote CNET - Ouch. The RIM BlackBerry 8800 almost took out the Samsung BlackJack in the first two rounds, but it really didn't have a chance. With its slim profile, a plethora of wireless and multimedia options, and solid call quality, the BlackJack simply overpowered the camera-less, 3G-deficient BlackBerry 8800. One can only hope that RIM comes back stronger with the rumored BlackBerry 8820. Until then, the BlackJack retains its crown.
