I got the battery for my 8125 yesterday, and spent several hours last evening setting it up. I can't say the situation was ideal. I had been waiting all week for this battery, and having a working Pocket PC meant a lot to me. My wife went out with her sister for a while, leaving me with the kids. I had school Thursday night, so the kids didn't see me at all. They missed me, I missed them, yet I also wanted to get this Pocket PC setup. I tried to play with the kids and install my applications and setup and test the 8125, but I can't say I did either well. My kids wanted me and I wasn't focusing well, so I ended up making the same mistakes over and over again. Eventually things calmed down and I was able to get enough of my favorite programs installed.
For the most part, I like the 8125. I definitely miss the large, 640x480 screen on my old hx4705. However, this device is built to run Windows Mobile 5 and it does run WM5 with a decent amount of efficiency, considering this is only a 200 Mhz processor. My last two Pocket PCs had 624 Mhz processors. This one has the 2.25 ROM update, so the OEM software is current. I might consider upgrading to one of the cooked ROMS on XDA-Developers.
I have to drive up to the University of Phoenix's Wayne, PA campus for a CLEP test today. I'm taking the Analyzing and Interpreting Literature CLEP. Next Saturday I take the Here's To Your Health DANTES test. If I pass these two tests, I should be good to go to complete my degree.
