I tried the Motorola Q, a similar PDA-phone, for a couple of weeks back in August and was definitely digging the ultra-thin form-factor.  What I didn’t like was that it’s too wide (the BJ2 is 2.3 in. wide versus the Q’s 2.6 in.), which made it less attractive for talking and perhaps pocketing.

The slim profile is a happy result of avoiding the ubiquitous slider, which only adds thickness to a phone.  After all, there are always tradeoffs, in this case between the practicality of the keyboard being always at the ready and in preserving the design line.

But what else is it that makes me want to buy a Blackjack II? 

Perhaps it’s the hope that Windows Mobile 6 will be better than 5: faster, handle Bluetooth connections better, more power controls. 
Could it be the upgraded features like a 1700 mAh battery, (as opposed to the 950 mAh that came with the BJ1) which I hope will be power plenty? (apparently, the power management is improved, too)
Maybe I am willing to excuse the lack of touch screen for the one-handed ease of using the jog wheel (i-pod style). 

And how about loving the integration of a GPS receiver, which is only now starting to appear on mobile phones?

Maybe I’m thinking that a 2.4 in screen is big enough, and downsizing from my 2.8 in screen is worth it to have the device thinness, save power, and have the keyboard always ready to go.  And since the resolution is still 320 x 240, everything will look razor sharp.
Could I be thinking about how I’d be able to rock 3G even on my Christmas trip to France, with the tri-band HSDPA support? (or even swap my SIM card into another phone, since it’s a GSM phone!)
Perhaps I like getting an IM and RSS client pre-installed, making the package more complete out-of-the-box.  And that there’s enough RAM to run everything (128 M.

And there’s nothing wrong with the fact that AT&T will throw in 1500 monthly text/IM/MMS messages with my data plan, whereas the big V is still clipping me at 10 cents a pop for messages going in or out.

True, the BJ2 is missing WiFi, but if my house is covered by their 3G goodness, then I’m fine with that.  I’m keeping my fingers crossed...
