As others have said...YRMV

In my case I bought the wifi version on pre-order and haven't touched my personal pc since. Having my IT guy strip it today and giving to my kids for school.

I recently picked up the 3G version (early fathersday gift) to take advantage of the unlimited 3G plan before it expired June 7th. I have it with me everywhere and use it for both work and pleasure. I handle 50% of my company email on it, have all important documents on file with GoodReader and office2HD and am able to take notes in meetings fairly well. The keyboard takes a bit of getting use to and I don't care for the lack of a good spelling/grammar check function....which just makes me work a little harder at proper English. (not always successful)I have the Bluetooth keyboard but haven't found a reason to open it yet. I use the multi media dongle for ppt presentations and just run them off of the iPad. I for one love it and can't imagine doing without it. I am able to leave my pc at the office and run with just iPhone and iPad now saving about ~7 pounds in my briefcase.

As others have said, browsing and media interaction are fantastic. The speed is easily 2x faster than my laptop. On another note, I tried to give my wife the wifi model to replace her pc....she just couldn't do it. She didn't like the keyboard or having to hold it rather than lay it in her lap (viewing angle) So the device is not for everyone, but certainly does the trick for me.

Again....YRMV.
