The Kodak Zx1 can't match the bare-bones simplicity of the Flip UltraHD or the rest of the Flip line of camcorders. Even so, the Zx1 has quite a bit going for it. It feels good in the hand, it doesn't succumb to a gimmicky USB-arm design, and it runs on regular AA batteries. It also records to removable SD/SDHC memory cards, which is a treat for anyone who already has a stockpile of them lying around. All this, along with the camcorder's $150 price tag, make it a compelling choice for a low-end pocket-camcorder.
