At first sight, nothing new under the sun, you'd say. The Inspiron Mini 10 still sports the same look - a look that I personally find quite attractive. You can opt for a 1.33Ghz or a 1.66Ghz Intel Atom processor, with a default of 1GB of RAM. There's lots of interesting optional equipment coming in the future, such as a built-in TV tuner, GPS module, and a HSDPA 3G module. You will also be able to choose between a 160Gb or a 250GB HDD.
The display is interesting. It's 10", but sports a 1024x576 resolution, which is better for 16:9 movie viewing. Still, it's less than other netbooks, and therefore Dell promised an optional 720p display, but whether or not the Intel GMA 500 chip can actually power HD content remains debatable. It also comes with a HDMI-out port, which is unusual for netbooks.
Shipping starts February 26, at 399 USD. For now, the model is Windows XP only, a Linux model is promised for "later this year".
