There’s no reason to feel tethered to a desktop PC to blog or add content to your WordPress site presence. Whether you are on the road in the south of France or commuting by train, you can use the offline time to add content to your blog/WordPress then “sync” your presence when you’re back in Wi-Fi range
iPad has BlogPad Pro and Windows has Windows Live Writer
My Windows 7 desktop and Windows 8 laptop both use “Windows Live Writer” which is a free download that is part of “Windows Essentials” free download.
The point is to make blogging as easy as possible, whatever the operating system, hardware platform, off-line or connected to wi-fi.
