It been couple of hours and finally all the apps have been downloaded now. The Plus is bigger, but to me it doesn't feel much different then the 4.7" screen. I haven't played with the duel camera yet and I totally have to get use to this 3D touch feeling. I'm having a hard time deleting and moving apps now. The new home button does feel different, no more pushing down and the taptic engine does fill pretty cool.
Tomorrow I will play with the new headphone lightning jack, it does look weird not seeing that 3.5m jack anymore, but I can get use to it. I can see the sorry part of not charging the phone, while I'm using the lightning headphone jack. To bad they don't have a duel lightning cord for charging and listening to music at the same time. But I do plan on buying some kind of bluetooth headphones soon to free up that part, probably this Friday when I get paid and plus there is a Fry's Electronics not far from my job.
I'll give more of a review later of whatever else I discover.
