While I know little about Everex or Via except for their older video cards and BIOS on Win95 and Win98 machines, It's not a bad idea. Nothing is said about who the MB manufacturer is, but odds on it's also VIA, considering that the chip has at best up to now a niche market. (This machine by itself will not change that).
Checking the Via website, I was dissapointed to see most of it hypeing "carbon free" processors. While the chip is properly a reduced energy chip, they get to the "carbon free" by buying "offsets". Hogwash. That's like me building an all electric, 24 hour lit, 6,000 sq. ft. mansion and calling it "carbon free" because I pay 60 peasants in China for the electricity they don't use. All the hype does is muddy the water.
As for longevity, one of those machines have as much chance of being trouble free as does a Core2Duo Quad chip in a PC from a major manufacture such as HP, Dell, or Asus. They are all electro mechanical devices, manufactured from assembled parts from a variety of sources. Murphy lurks in the cases of all of our PC's, and spending time in the support forums just reinforces that.
If this machine provides an avenue for income limited individuals to be able to get on the internet, and keep in touch with friends and loved ones it is invaluable. Will it suppy the needs of the young college crowd who wants the latest and greatest high powered game? No, but it may supply the needs of those who want just the basic needs. There are people out there still happy with P3's running Win98. I have one. I also have a P4 with XP Pro and an C2D with Vista Home Premium. Each has its place and serves a need.
A family is more likely to spend $300 for a computer for their 8 year to use, than $1,500 which most of us consider as a budget for a reasonable machine for our wants, not our needs.
