While I could use the Diamond WR300NR to overcome that problem while traveling, I might also need a few extra USB 3.0 ports for my various drives and peripherals. The newly announced Diamond Multimedia USB303HE fits that bill to a tee. From a single USB connection (no need for external power), you get a three port USB 3.0 hub plus a 10/100/1000 Mbps gigabit Ethernet port. That's handy!
I can see how this could be a great companion device on the road, particularly when you get to hotel rooms that lack wireless Internet. And just having some extra USB ports is never a bad thing. The USB303HE is shipping now for $39.99, available through such retailers at Amazon, Fry's, NCIX, Newegg, Future Shop and Best Buy.
