I've been wanting both Swype and Google voice input as options on my PC as they both rock and I love using them over tapping away on a keyboard these days and I finally figured out how to do it!
I installed something called a "touchpad app" on my tablet and phone, then installed a server on Windows to host the touchpad via Wifi.
Next thing you know, I can use Google voice to flawlessly input entire paragraphs on the tablet that now show up in the input fields on Windows! I can also use Swype to type which is kind of cool on it's own, forgoing my normal keyboard altogether. Additionally, the touchpad works great in the browser as now you can pinch, zoom and scroll just like you do on the tablet and it's very natural feeling.
It's the closest thing you can get to having a 24" touchscreen without buying a new monitor.
