hey... I saw your post and wanted to make a quick comment regarding a new screen protector. When I received my Zero about 8 months ago, I immediately got the screen protected with a custom-made, tailor-cut film sealed over the front to prevent damage, etc.
If you happen to live near any mall that may have this type of service offered, I would look into it as it would benefit the longevity of its life, etc. Personally, I used a service called Ghost Armor at a nearby mall where I live within the USA.
Hope this helps.
