I've never had the 205, but I do have E105 and E715. In my opinion the E715 is a very nice phone. I went to it from my old T720i. That phone was very slow compared to this. The only problems I've seen so far were reboots due to some bug in the browser, low battery duration (some people have good time, some don't). My phone can do standby for close to 4 days. I never tried talking for 4 hours in one day since I don't use the phone THAT much. My T720i's standby was about 5 days on regular use compared to this, so I don't think it's bad. The camera is nice also. All in all it's a very nice phone.
