Then you should head over to Custom Evos and put down $14.99 for the clear battery door that xda-developers forum member joey3002 is trying to get into production. What you're looking at on the right is a prototype, but the final version will look very similar. The door/cover features raised rails and a small logo set inside a circle to keep the main surface and camera lens from getting scratched when placed on a table.
The manufacturer needs about 150 to 160 orders before putting the covers into production. There was about a third of that a few days ago, so joey3002 and everyone who already placed an order could use your help. Without the requisite number of orders, the project obviously can't move forward and people can't get their battery doors (full refunds will be issued).
Free shipping in the continental US and discounts on multiple units are being offered during the preorder period going on now, so don't wait too long if you want one. There are also red, blue, and yellow covers available if your EVO is a prude and doesn't want to be so exposed in public.
