"The slot accepts cards with a capacity of up to 32 GB."
I researched this before buying the ATIV S in November. Although I forget the exact details, the 32GB limit is a software or firmware limitation, not a hardware limitation. Samsung specs for the ATIV S list SDXC compatibility with no stated upper limit, though SDXC itself has a 2TB limit. My point is that the 32GB limit on microSDHC and microSDXC cards for this phone will very likely disappear with a future version of phone firmware and/or Windows Phone 8 software.
"Currently the ATIV S cannot offer LTE"
I purchased my ATIV S in November in Canada and it came with LTE. And the LTE works well, as I regularly use it on my Canadian carrier's LTE network.
