No. Wireless adapter needs better power source, so it's RPi to powered hub to WiFi, which makes the setup quite a bit bulkier and pricier.

Like gp I wish some sort of network connectivity can be included to make it more complete as a standalone computer.

Nope, we have hundreds of Pi2's with two wipis in them, yeah it's fine.

You don't need a hub, you need a smartphone charger (one that gives you more than 500mA at output).
