The amp is a bit weak, i agree. But i think it has something to do with battery saving feature. Well, afterall it is a phone... When you transfer the song do you use card reader OR with Sony Ericsson built in PC Suite (with the phone attached to PC)? As a long time sony ericsson (and ericsson) user i have to say that they have the worst PC Suite scenarios regarding file transfer speed. The phone connector hardware (called Fast Port) actually support USB 1.1 (some might say USB 2.0) BUT the program came from its PC Suite use a serial emulator when connect to the phone. I dont have hard data to prove this but the file transfer speed still not improving since t68. It has something to do with the program called Mobile Phone Monitor. SE havent heavily upgrade this connection software. Basically it is still the same that T610 use. Comparing other PC Suite, eg Nokia, which truly support USB, the margin is noticeable. So i think, until now, Memory Stick Media have an adequate file transfer speed. If you use card reader (even with USB 1.1) the file transfer still outperform the PC Suite in large margin. If you planning to manage your music file i strongly recommend a card reader to move the files in and out instead replacing your MS.
