Frankly I think what cannibalizes their high end sales is picking up last year's model on Swappa or even used on a carrier's site.
We'll see how much of a value price point the S10e comes in at, but I'm guessing at least $700, so not much of a mid range value.
LG could really offer an attractive alternative, but they price their flagships just as high as Samsung, but then drop in value even more months down the road.
Interestingly Sprint is using the 5x5 G-block as the PCC and 10x10 B-block as the SCC for carrier aggregation here in Boston (Chestnut Hill). I can't complain though because the download speeds are insane. I never thought I'd see the day I'd get speeds like these on Band 25.
Edit: I should add that this was taken indoors.
