What you may not realize is that the Atom has two common versions, the N-series and the Z-series. The Mini 10 netbook uses the Z-series. The primary difference between the two versions is that the Z-series features a chipset with a better graphics processor in it. It's a better match for Vista's GPU-accelerated desktop, though we wouldn't recommend trying to run Vista on this system. More important, the Z-series chipset supports the kind of video acceleration technology that makes it possible to play back video reasonably smoothly (something the Atom N-series doesn't do too well).
The Mini 10 with the Atom Z530 processor (1.6GHz) that we tested costs $534 as configured. The price puts our Mini 10 beyond the usual upper limit of a netbook (though units start at under $350). In addition to the Atom Z530 processor, our test unit had 1GB of soldered-on RAM, 802.11g Wi-Fi, an ethernet jack (10/100, not gigabit), three USB ports, headphone output, mic input, an HDMI-output, and a slightly higher-res screen than most 10-inch netbooks (1366 by 768). Frankly, the extra resolution doesn't do much at this size, and you'll find yourself squinting to read on it. You could always increase the size of icons and fonts and such, but Windows XP doesn't handle such resizing very gracefully. The reason for that video kick is in no small part due to the optional on-board HDTV tuner that came with our unit.
Yep, this nondescript input jack sits somewhere between a USB port, a combination SD/Memory Stick card reader, and a power plug on the left side. It seems a little out of place, but the internal Hauppauge WinTV MOD7700 ATSC tuner meshes pretty well with the included Dell Digital TV software. As long as you get a decent signal with the included antenna, TV video plays back fairly smoothly. But why put a TV tuner in a netbook? It makes sense in a larger notebook where you might want to record TV and then watch it on the road, but the small, slow hard drives in netbooks are no good for that. You actually have to pull the tuner and the antenna out and hunt for a signal. It'd be easier to find a real TV.
The video decoding in general (TV and otherwise) is mediocre--HDTV channels are just a little choppy, and standard-def channels need to be cleaned up a little. And the real problem is that the GMA500 integrated graphics doesn't do anything for most Web video, like Hulu or YouTube. Watching even standard-def YouTube videos at normal size in the browser window was such a choppy mess that you want to stop watching in seconds. Now if Dell incorporates this feature into a Ion-based netbook, that would probably make all the difference.
The 10.1-inch screen actually looks a little small on this system, in part because the body is large enough to accommodate an 11-inch screen. A lot of border surrounds the screen, and that doesn't combine well with the relatively high resolution and small size. It only exaggerates the impression that you're straining to read the screen. But in actual visual quality, the screen is surprisingly decent for something so small and cheap, with reasonable contrast, color reproduction, and viewing angles.
