Excerpt: When Dell debuted the Axim X5 last year, we thought it was a well-priced PDA in a too-large package. The company has remedied that with the Axim X3i line. Three trim levels are available, starting at just $229 (direct). We tested the top-end model, which features a 400-MHz processor and integrated 802.11b wireless. At $379, it's the least expensive Wi-Fi–enabled Pocket PC 2003 device.
