I think it depends on your needs for performance. Most personal applications (streaming music, video or storing backups) aren't going to be affected much from having a 2 gigabit link.
At 10 watts, there is a good opportunity for some power savings. I have an Atom-based HP MicroServer and it lives in the area of 30-40 watts idle with 5 3.5" drives. Going down to 10 watts would mean saving around $40/year for me, not bad, but not enough to worry about.
The biggest failure with this in my mind not supporting 3.5" drives. Getting decent capacity in the 2.5" form factor is not really possible, and if using SSDs, in that case you'd want a more performant machine like you describe. Then again if using SSDs, why not just use an even smaller form factor.
