A review of the Samsung M610 clamshell phone has been posted over at Laptop Magazine. 'Unlike its predecessor, the M610 comes with a microSD memory card slot. Too bad it's located underneath the battery pack, which means you have to power down the phone to access the card. We figure this was a necessary shortcut to facilitate the phone's thinness, but anyone who frequently swaps out memory cards will find this implementation to be annoying.
The M610 uses a proprietary headphone jack/charging port, which means you can't plug in your own earbuds. Instead, you'll have to use the supplied set, which delivered loud, crisp sound but got uncomfortable quick. Then again, at least Sprint includes earbuds; both Cingular and Verizon charge extra. Plus, you could always go wireless by pairing the M610 with stereo Bluetooth headphones. (At review time, we had trouble pairing headphones with the M610; however, we suspect our test headphones for the anomaly. We will follow up testing as soon as we can.).'
