For a Zigbee option, I have a UseeLink Zigbee Power Strip and it works well for me with a custom driver I wrote for it. Unfortunately, it seems to be out of stock on Amazon (where I purchased it) now, and if you're in the US, I can't find any models elsewhere with standard North American plugs. I also have the Zooz ZEN20 mentioned above (both the original and v2), and that works well for me, too. It seems like there aren't a ton of options here. The Aeon SmartStrip is one of few others I know of in this category, and aside from apparently being discontinued, it was less preferable than the Zooz to me because I think every two outlets were "grouped" and that was as fine of control as you got, whereas Zooz gives you control over everything (except USB). If you only need two plugs, the Zooz ZEN25 is another option, and there are or at least were a few whitelabel-looking dual Z-Wave plugs out there, too.
I don't see that anywhere in the changelog, and I don't think I've seen that mentioned anywhere before (and I'm on the latest 2.02 firmware that the "original v2.0" of this hardware supports). The UseeLink actually does provide USB control, but this is pretty rare (unheard of, I think?) on Z-Wave power strips--and most in general--from what I've seen. Luckily, I have little need for this--just thought I'd mention it anyway.
Not as pretty or compact but at this point in time I think your best bet is to head off to IKEA.
5@$15 for a Zigbee outlet= $75, plus a $7 set of power bars, $82+tax is about the cheapest option.
And of course down the road you can separate it up into five smart and twelve dumb outlets if so desired.
