Samsung has just days to go before the Series 5 Slate (and ATIV Smart PC) arrives hand-in-hand with the official launch of Windows 8, so we're surprised that it's been waiting so long to clear the usual regulatory hurdles in the US. Just in the nick of time, though, the 11-inch tablet has passed by the FCC for approval. There's no hidden surprises to go with the testing -- this is the regular Series 5 with Bluetooth and dual-band WiFi, but no visible NFC or the AT&T model's LTE. As such, we're more curious about when Samsung's Series 7 Slate and Series 5 Ultra Touch reach the FCC's doors. They'll likely arrive soon, but any significant delay could put them on the sidelines for Microsoft's big moment.
