As far as adapters go, the UL20A's weighs slightly more than the one that belongs to the 1215-series. Oddly, we should note that the micro plug on the Eee PC is fairly nonstandard. If you are shopping around for a universal extended battery or a universal power adapter, you are almost certainly out of luck on the Eee PCs. We have yet to find one that fits. The UL20A doesn't suffer from this issue.
People don’t usually consider adapter profiles. With netbooks, we are looking at small power bricks. None of the wires coming out of the power bricks are angled, so cable management can get kind of ugly.
The 1215N gives you more minutes per computer pound. To be fair, part of this is due to the fact that Asus put higher-density cells into the 1215N (2.9 Ah). However, the Optimus technology at the heart of Asus' 1215N gives this configuration the strength of Intel's power-optimized architecture, and that puts it over the edge with a clear lead.
