I hope a good bigger mah battery comes out soon.
does anyone know if these aftermarket 1500mAh last longer then the stock 1350?
1500mAh Battery+Desktop Dock Charger For HTC Inspire 4G - eBay (item 370484776473 end time Mar-17-11 03:40:08 PDT)
Stock on the Inspire is actually 1230. As for the link, I don't know - their description specifically states "Best replacement for the original battery with comparable standby and talk time."
So, the way it sounds to me, you may not be gaining that much extra time even with the extra battery size.
Also, despite the overall good reviews on the seller, my cynical nature gives me pause over a "larger" battery that is being shipped directly from China for $9.00 total. But that may just be me.
