Keyboard: I thought that the keyboard would really bother me. Many of the keys are moved around from the kbd on the 8525, which I was used to. The FN key (Blue dot) was moved to the middle of the left side and the OK button was in it's place. I thought that i'll be closing my messages while in the midst of entering them. I also thought that they COULD have made the new 5th row emulate a PC keyboard and put the numbers row up there instead of having to FN them. After using it for a bit, i found that HTC/AT&T placed the most used keys (even the special characters) on their own keys, so you can punctuate and :) ;) without having to shift or FN them, therefore the likelyhood of my hitting the end key instead of the formerly located FN key is more remote.
TouchFLO: I keep hearing people complain about how slow it is, how non-configurable it is, how it will not do this or that... It is ONLY a free desktop app not the device's only interface... If you do not like it, turn it off and go with the standard WM desktop and do what you want with it as you would have done had HTC not given it to you for free, as WM enthusiasts have done since CE3. You could buy MobileShell and PhoneSuite, both are very good apps... They are not free however.
GPS: There are some issues with GPS. I don't know if it is a hardware implementation, driver issue, software, weather, poor satellite coverage or a combination of the above. Some people with the same configuration have no problems, others cannot get it to do anything functional. In my experience, I find occasional lag in the updating of position in driving navigation apps, but it is typically accurate. Walking or hiking apps are another story. The lat/long/alt seems to update, but headings are not available... I find it fine for being a co-pilot, not so good for geocaching/hiking.
Camera: The camera seems much the same as other cell cameras, but with a higher resolution. It still never gets enough light, backlight will wash out the whitebalance, the autofocus adds about 3 seconds to the time it takes to snap a pic. It would have been nice if the devs at HTC made the flash autoenable, you know, like every $15.00 camera in the world does... It even has an integrated light sensor, perhaps they could try and use that... It isn't a BAD camera, it is probably better than most cellphone cameras, but it will NOT replace a even a cheap digital camera. I haven't bothered to take video with it, I don't expect much beyond the typical grainy-jerky motion that all these cameraphones generate.
The Screen: The VGA screen is absolutely beautiful. I had forgotten how nice a VGA device looks. The black is a true black and the screen finish looks amazing. Hopefully, it will remain unblemished and durable for the life of the device. The screen is only a tiny fraction smaller than the screen on my 8525, while to overall dimensions are significantly smaller (as shown in Chris' execellent review). The screen requires a fair amount of pressure to make it respond, although there are some tweaks around to modify that somewhat. I haven't tried any real video to test the graphics performance, but it is easily suitable for flash animation and youtube videos. The finger touch sensitivity is fine as are the enlarged menus and interfaces. My only difficulty is the right side vertical scroll... I have a hard time with my fat fingers making it go.
Buttons: HTC removed the hardware "soft keys" and the scroll wheel is unusual and infrequently implemented. Unusual means that instead of the "wheel", you have to rub your finger in a circular motion around the center "enter/action" button. It isn't implemented by many apps and when it is, it is usually does something stupid, like changing font size. There are 3 hard buttons on the side, factory configured for vol up, vol down, and PTT. There is no simple way of changing those assignments, the only configurable button on the device is long press the hangup button. This makes the purchase of AEButtons Plus a necessity. That will allow the remapping of all the hard buttons on the device. I have vol up=startmenu, vol down = alt-tab, ptt short = voicecmd, ptt long = camera, and the default long press hang up = vibrate toggle.
Audio: I just noticed something unusual with the audio. I have a BT stereo receiver connected to a cassette adapter, so I can play audio from the PPC to the car stereo without wires (I posted the setup in the BT forum a few months ago)... That is fine and that works as expected. However, I also had Garmin Mobile XT running so it could show me the way home and all the audio from it came out of the loudspeaker, not though the BT audio into my radio. I had a similar setup on my 8525 using iGuidance and the spoken directions came out as did the music via BT. I don't know if this is a hardware feature where the Fuze can manage multi-channel audio or Garmin is forcing it out of the loudspeaker regardless of the other connections. It isn't wrong, but it is different and might be an issue if you were listening to music on your headphones and it started broadcasting "you've got mail" alerts into the room around you.
LED Indicators: If you were familiar with my Rules for Technology, one of my biggest issues was the overabundance of bright flashy LEDs attached to things for little to no purpose, like BT headsets with blue LEDs so bright it looks like they have a disco on the side of their head. On the Fuze, there is only a backlit area around the center enter/action button. it has a progression/movement pattern when showing a notification and a slightly differnt one where the phone "dial" button also backlights for a missed call indication. It is very subtle. The only other LED indicators are VERY tiny LEDs on the hardware keyboard for FN and Shift indicators.
more to come as I sober up...
All in all, I LOVE this phone... Nothing else has pleased me more than breaking up with my with my ex-girlfriend
