Er, no. The 7 is stupidly expensive still and actually offers very little over the SE other than the bigger screen. There's no great performance difference. Both have the same RAM. The A9 has fewer pixels to push and is still a very strong chip (also the backbone of the new iPad so will be supported for many years). The SE itself will carry on until next March at least before any replacement is in sight, whereas the 7 will be reduced to last years model in a matter of weeks, the big difference being that the SE is stupidly cheap now but they're still pricing the 7 like a brand new flagship.
I think the SE (especially now with the bigger storage options) is the best value for money product Apple have offered in a long time, and I'd recommend people jump on it while it lasts.
Battery life, one handed use, headphone jack - all big plus points for the humble SE.
