The only weakness with the S5 was the charging port having a cover that could easily break off, but modern ports these days are waterproofed, so they could just make one of those.

Personally, if they remade the S5, with a modern board and charging port (rather than the Micro-USB 3.0 monstrosity), I'd be very tempted to buy it. The IR blaster and everything else was just nice to have.
