You might think your smartphone is pretty brainy, but is it clever enough to essentially replace your laptop while on the go? Salt Lake City-based Celio is betting you want a bit of both devices at the same time. It has come up with Redfly, which looks like a tiny laptop, but is actually a keyboard and screen that harnesses the processing power and storage space of smartphones that use Microsoft’s Windows Mobile operating system. It does enhance some phone features, but given its price, relative chunkiness and limitations, I won’t ditch my laptop for one of these just yet.
