hard to say. My experience is different than many others.
I have had my explorer for around a month now. In that time I have not experienced any major issues with MFT.
in fact, I have personally had my iPhone be more of an issue that my MFT
It has never rebooted on me, gone into service mode or black screened.
With that said I still worry about it sometimes. I questioned upgrading from 2.4 to 2.11 because I wasn't having problems. I upgraded and it's been fine with a minor issue of not getting text notifications.
I worry that I could walk out get in my Ex and have all these things happen, but so far mine has been fine.
The voice stuff can be annoying and I would prefer knobs for many things, but I really like my Ex as a whole package.
Good luck on your decision.
As of now, my MFT is working great - taking it one day at a time.
