The W-series has done really well in the past couple years, blending a diminutive size with stylish brushed-metal body and snappy performance. The W620 comes in at $10 more than the W610, yet we aren't sure that's money well-spent. The zoom gets an upgrade to 5x, yet loses the wider 26mm and f2.8 of the W610. The camera is also quite a bit larger and still doesn't have image stabilization. 720p HD video is included, however, so if that's a necessity then $10 extra is probably worth it.
