Apple Accidentally Leaks 'MacBook Neo'

This is a most excellent place for technology news and articles.
That chassis hasn't been for sale for 4 years, so judge repairability on what they sell now. And regardless of sourcing it from Apple or not, you can easily source the battery.
Yap, newer models use those strips, my bad. Although, I disagree the inability to source stuff from the manufacturer isn't a big deal: batteries made of chinesium tend to fail really quickly, up to the point I started replacing just the cells myself with known good quality ones after a couple of batteries failing in like half a year. However, I suspect apple should sell batteries for said newer models, since they've made 'em replaceable.
