OK now for a battery report, day 2 of using my my Treo 680 with Seidio's extended battery and so far after numerous cell phone calls, email via snappermail, three instant message chat's, QuickNews RSS feed downloads and a document type up in Memo I now have a very positive 98% battery power left after charging the Treo last night. So far so good, very pleased. More details on the battery from SeidioOnline.
