The star attraction on the Dell Axim X51 is undoubtedly its 3.7-inch VGA screen. Thanks to a 640x480-pixel resolution and a 16-bit-color output, you'll enjoy sharp text and images, and there's continued support for landscape and portrait modes.

The Dell Axim X51v's biggest makeover is in the features department. Some elements remain the same, though, such as the 624MHz Intel XScale PXA270 processor and the Intel 2700G graphics engine. Also, there's still 16MB of dedicated video memory and 64MB of SDRAM, but the really good news is that Dell bumped up the flash ROM from 128MB to 256MB, 192MB of which is user-accessible. This, coupled with the dual expansion slots, amount to ample storage space. Another thing that helps is the addition of the Windows Mobile 5 operating system. The new OS has built-in support for persistent storage, so when the battery drains completely, your data remains intact.
With Windows Mobile 5, Microsoft also swapped out Pocket Word and Pocket Excel in favor of a new Office Mobile Suite that includes Word Mobile, Excel Mobile, and PowerPoint Mobile. Yes--PowerPoint. Although you can't edit slides, you now can view presentations right on your PDA. We gave it a whirl, and we were impressed not only with the ability to watch slide shows but also with the various options. You can skip directly to specific slides, change the orientation, and choose playback options, such as loop, turn off/on animation, and zoom in/out. The last option is particularly handy, since a thumbnail of the slide is presented in the lower-right corner of your screen. What's more, you can choose particular spots on the page to zoom or automatically go back to the full slide. Unfortunately, these tasks seemed to take a lot out of the Axim X51v, as there was a noticeable delay in response time (see Performance). As for the other applications, Word Mobile now supports documents with embedded images and tables, plus Excel Mobile handles charts. We put these applications to test, and while the experience was not ideal, given the size of a PDA's screen, we were able to open and view tables and charts in all our documents.
