As a Windows Mobile fanatic, I had to buy this phone. This is actually only my second Windows Mobile Phone. My first was the Audiovox XV6600 through Verizon Wireless. I had written a review on that phone and at the time thought that the XV6600 was a good phone. Boy, does the 8525 blow that one away!!First off, I love the form factor. Even though I am going from a 3.5" screen to a 2.8" screen, every thing is still clearly visible. I will say that it is a bit thick and heavier than most phones, but not objectionable at all. The 6 buttons surrounding the D-Pad are a bit small for my liking. HTC's TyTn (which the 8525 is based off of) has a better button arrangment in my opinion. Also, the TyTn has a forward facing video camera for video calls. Too bad AT&T; did not incorporate that cosidering they just rolled out video calling! The QWERTY keyboard has a nice tactile feel and the lighting is evenly lit in dark environments. There is a MicroSD card slot on the lower left. I was concerned at first that I would accidentally pop the card out, but I have not yet. It is recessed enough to avoive accidental removal. The scroll wheel on the top left is a great feature. It makes one handed use possible and easy.As you all probably know, this is a Windows Mobile 5 phone. It has 128MB of ROM, but unfortunately, only about 52MB are available for use. This is due to the OS and other AT&T; software being loaded on. I wish AT&T; had instead, put their software on the included CD-ROM or as a link to download, therefore saving us space. Oh well.The phone itself works great!!! I live in Conncticut and have never had a dropped call or hit a dead area yet. The sound quality on this phone is excellent. On my XV6600, I would struggle to hear the other person, but on the 8525, I have to turn the volume down because it is so loud. I also have purchased an unlimited data plan and fortunately for me, I have 3G access almost everywhere I go. And if I don't have access to 3G, I can turn on the wi-fi radio to access faster data connections. Lastly, this phone has Bluetooth 2.0 with the A2DP driver. This is great since I just bought the Motorola HT820 to listen to music and take phone calls. The included headphones aren't that great. Also, you'll notice that it uses an extUSB connection for the headphones. If you want to use regular headphones, you'll have to buy an extUSB to 3.5mm adapter.Battery life on this phone has been excellent as well. I have managed to go a whole day with this phone and only get down to 60% battery level. And that was with using the Internet, MSN Messenger, phone calls and checking emails. It comes with a mini-USB home charger and a sync cable to charge/sync with your computer. Unfortunately, with most PDA's today, it did not come with a cradle. I like having cradles, so I purchased one from Boxwave and it works fine.There are so many other features on this phone that makes it a wonderful converged device. What's missing or dislikes of mine? I wish it had GPS built in. It could also be a little thinner and lighter. More memory and a true 3.5mm jack would have been nice. Fortunately most of these shortcomings are going to be addressed by the HTC Kaiser, the replacement for this phone hopefully coming at the end of this year. The Kaiser will add 256MB of ROM and 128MB of RAM. It will be thinner, GPS built in, and a screen that tilts up!!!Overall, I really love this phone! I highly recommend it to anyone in the market for a PDA/Phone combo. Though, if you can, I would wait for the HTC Kaiser coming out soon. I WILL be getting that when it comes out.
