No need to be tempted by Android. These old school copy cat PC and old cell phone companies, like Samsung, will continue to make crappy hardware and have no clue how to do software and UX worth a damn.
I think Android’s only shot at decent hardware and software is what Google might do with their Motorola Mobility purchase. That combo might actually be able to invent something new and finally create an innovation. Instead of just copy (steal from) Apple. I won’t hold my breathe. But if its possible, it will probably come from them.
“The overall consensus is that the Galaxy S4 is a solid upgrade over the previous S3 but that its plastic casing and minimal upgrades keep it from being great.”
