Sony Ericsson :: Device That Will Receive Updates And Adding Features

So, I saved up some cash, and am selling some stuff to get about 300-350 pounds budget for a new phone. I'm very tempted to get the N97 mini. It has good audio quality (gsmarena tests) pretty decent pictures, WiFi, GPS, qwerty keyboard and a nice screen. What does SE have to offer that will give me good music, photos and connectivity? WiFi is pretty important and a qwerty keyboard is a big plus. Another thing that stops me from spending so much money on a brand new SE is their lack of updates when it comes to fixing bugs and adding features.

I still see Nokia pumping out N95 firmwares that get new features and fixes. The SE phones I owned could've got new features but SE never bothered. Take smile shutter on the C510 for example, they could've and in my opinion should have also made an update to include the feature in it's bigger sister the C702. But they didn't. I don't want to spend 300 pounds on a device that will not receive updates and features after 6-12months.
