I tested Kyocera's Slider phone for over a month, and the novelty (i.e., feeling like I stepped onto the set of The Matrix every time I used the thing) never wore off. To dial, you slide the phone's faceplate up, which exposes the keypad. To end a call, you slide it back down. You can also end calls by pressing the designated button, but sliding it shut is all part of the experience.In addition to the Slider's (many) standard features, the V5 MTV Edition, the one I sampled, includes access to content from the channel like news, ring tones, trivia, and screensavers. Virgin Mobile struck a deal with Kyocera to market the MTV edition exclusively through its pre-paid service plans. The non-MTV version of the Slider, the SE47, is currently available through MetroPCS and US Cellular. Kyocera has plans to roll out the SE47 with an undisclosed carrier next month. The verdict: If more popular carriers like Sprint and Verizon started adding the SE47 to their rosters, they'd fly off the shelves - and I'd be the first in line. Any questions?
