The idea of the Redfly goes thusly: Take the netbook form factor and then turn your smartphone into that form factor by "tricking' your it into thinking it has a larger screen, full keyboard, and mouse. It's an idea that we've been pretty fond of, but frankly we're not the sort to leave the laptop behind.
Enter Redfly Mobile Viewer, which takes the same basic idea and jettisons the Redfly hardware in favor of an app on your Windows PC. Think SOTI Pocket Controller with an added twist: instead of merely duplicating your smartphone on the PC, it actually convinces Windows Mobile it's running on different hardware.
Actually, never mind the details – the upshot is that you can have a window on your PC that is your smartphone – only enhanced with a 1024x768-sized screen, your PC's keyboard and mouse. It might just be a nice solution for some Mobile Accomplishers out there who want to keep as much of their work as possible on the smartphone and/or who don't want to bother tethering.
It is a Beta, however, so it's still a little twitchy here and there (see: browsers). On the bright side, Redfly has announced compatibility with 18 more smartphones and also sped up its software a bit.
The Beta is free and just might be worth a shot. Learn more over at CelioCorp.com.
Update: Phil takes the Mobile Viewer for a spin after the break.
