When I am interested in a product, like you normally I do some research on it 1st. I go to forums expecting to read the pros & cons. Unfortunately, for the most part lately there has been a ridiculous amount of misinformation posted in these forums. Obviously, forums are filled with posts & threads from people that express their opinions of a specific product. I have no problem with that at all. I know how to filter through posts that are BS. I don't have any problem with differences of opinions, nor a problem with someone out there doesn't like this phone or has had a negative personal experience with it....but I do have a problem w/ false or incorrect information. Take some time & read through as many threads in this forum as possible. Especially posts by dishe, tcaudill01, hoovhartid, & myself (nosajsam).
with that said, let me try to help point you (& others) in the right direction
As one of the 1st to have this phone around here I can say that I still love it. I have a Sero plan on Sprint & for me this is a great 3G device that keeps my plan @ $40.00. I found (like many others) that initially it isn't buttery smooth out of the box...but that can be fixed very easily (by installing a different launcher). The screen is great & imo so is the size of the phone.
CAMERA
I like that it has dual cameras & having a flash is a big plus. (Here are some pics from my phone)

ROOT
The phone can be rooted very easily (see post here)

BATTERY LIFE & CHARGING
Yes, there are phones out there w/ better Battery life. The battery life of coarse depends on the user but with a few easy tweaks (shutting off things when not needed/being used) 18-24 hours of battery life is possible.
Check out this very helpful post with really good tips on how to improve the Battery life of this phone.

I applied most (not all) of the tips & I am consistently able to get 18-24 hours of pretty steady use without having to recharge. I always keep a charger nearby anyway.
Brightness - If you keep the phone at 100% brightness, your battery will drop quickly. If you can adjust it & keep it lower it may help improve your Battery life.
Keeping the Data Sync, GPS, Bluetooth and Wifi are on (even they aren't being used) will drain the battery. Shutting them off when not in use will help improve Battery life. There is a free power control widget that comes with the phone but for more customization options, the EXTENDED CONTROLS App is recommended.
For best charging performance be sure to USE THE STOCK CHARGER

LG Marquee, AC/USB Charging, and YOU!
After reading the link I posted above I installed Battery Monitor Widget & found that some of my aftermarket chargers & cables were not working well with this phone. Once I determined which ones worked best, I uninstalled the app.
Apps such as BATTERY MONITOR WIDGET, JUICE DEFENDER, & TITANIUM BACKUP are great & do their job well. Before I installed these apps I was getting a consistent 18-22 hours battery life & didn't see much improvement after I installed them....so I took them off.
