I have never owned the Envy and I have owned the SCH-U740. Not sure on what you are going to be using the phone for mostly, but if you plan on texting a lot I would go with the Envy... Being that the 740 is a much smaller phone, it is ONLY capable of holding 50 text messages. Also another thing you may want to keep in mind is the battery life of the 740 wasn't great. That is part of the reason that I did an early upgrade to the Voyager. They do NOT offer an extended battery for the 740. Also I have always been super careful with all of my phones, but I had dropped my 740 one time, and it wasn't even a very hard hit, and that was enough to take HUGE chunks of plastic out of it.. I didnt find it to be very durable at all... Way too fragile for my personal taste. As much as it is ok for texting, the close placement of the buttons DID pose a problem for me as well and I dont have really big fingers..
