I was one of the lucky ones to get my Incredible yesterday, so I've just finished my first 24-hours with the device. My last phone was a BB Storm and the phone before that a Motorola Q (both first gen, so I deserve this Incredible). I had no experience with Android before yesterday. Here are my initial observations in no particular order:
The phone is not heavy. I think that is why some people might think it feels plasticy, but I think the fit and finish is superb, and the overall construction solid. The screen is excellent, but very hard to see outside. Maybe there is a setting for brightness that could help outdoors, but I have mine set to automatic so I'm assuming it is boosting brightness when I take it outside. The camera shoots fast, and the pics look great so far. Videos shoot and playback great. I haven't played with all the settings yet, but they seem very easy to use. I was extremely impressed with the setup of the device. My office uses Google Apps, so I'm sure that eased some of the pain, but within seven minutes I had my work and personal email set up, and my calendar and contacts synced. I entered a few user/pass combinations for various sites and it set up my facebook and started matching my contacts with their facebook profile pics. I popped my SD card straight out of my BB and into the Incredible and bingo, photos, videos and music were all sorted out. A friend called me and immediately asked if I got a new phone! I said yes and he said it sounded ten times better than my Storm. Last night I played with some of the stock apps and voice to text input and it is amazing. Downloaded some stuff from the App market like Google Sky Maps and that is downright incredible (you didn't think I'd make it all the way through this without one, did you?). Today is the first day I can test battery life, so I will hold off on judgment for now. Being used to keeping an eye on my memory resources on the Storm, I'm kinda interested to see how much what I'm doing is taxing the device, but I haven't figured out a way to do that yet. I'm trying to tell myself not to concern myself with that, as I haven't experienced any slowness, lags or anything but pure speed. The browser is the biggest single improvement over the Storm. It loads quickly, renders properly and has had no issues with any of the sites I've visited yet. I didn't realize until I maxed it out, that it has multiple browser windows. The optical trackpad works very well. I still don't know how much I'll use it, as the touch is perfection, but I do like having the option. My wife and daughter just loved how my phone had rain drops on the screen yesterday because it was raining outside yesterday - which I also didn't have to set up. I just allowed it to do location based stuff and it put the weather on the home screen.
I know there is a ton of stuff I haven't even discovered yet, much of it probably stock Android, and as for that, I can't wait. This thing is miles beyond BlackBerry.
I did already break a small piece of plastic that surrounds the USB port. BE CAREFUL inserting the cable, as the plastic surround piece is tiny. I'm probably just a dolt, but clearly that area of the phone will get abused over time, so I think that piece should have been made more sturdily.
