Now, though, if you peruse the EPEAT registry for a green "tablet notebook," you'll come up with one listing: the Xplore iX104C5 DMSR. No iPad, no Surface, no Kindle, no Galaxy. So what gives? For starters, the Energy Star spec briefly covered tablets, but not anymore, which means no tablet can be slapped with an Energy Star or EPEAT sticker. Energy Star is working on a new spec that will likely include tablets, while EPEAT is working on new criteria as well. But also potentially problematic is that some vendors — particularly Apple and Microsoft — aren't designing their tablets to be easily repairable, as evidenced by iFixit's Tablet Repairability scorecard. (Dell, by contrast, is doing an admirable job.)"
