The 3G-enabled QWERTY smartphone market is finally starting to get a little crowded -- and that's a very good problem to have. Of course, that makes picking one out a bit more challenging (trust us, we're still not complaining) and it always helps to rock out with a nice, old-fashioned comparo now and then to separate the wheat from the chaff. This time around we have the Samsung SGH-i600 (alias i607 BlackJack in these parts) going up against the as-yet-unannounced HTC Cavalier, successor to the Excalibur / T-Mobile Dash. On paper, the two are nearly dead ringers for one another, with the major differences being a 2 megapixel cam on the Cavalier (versus a mere 1.3 megapixel piece on the i600) and a slight thickness advantage on the Samsung. Ultimately, the reviewer had the Cavalier coming out on top -- despite the fact it's not even available yet, suggesting the test was conducted with a preproduction unit -- though the i600 was nipping at its heels throughout. Bottom line: it seems like QWERTY lovers are going to be happy with either one, and with the HTC still at least a month or two from release, our impatient selves will take what we can get.
