I love my iPad mini - in fact, I find myself using it more and more for most of my day to day work and even my home business work. Now that I have a Zagg keyboard for it as well I find it even easier. Some of the research I've been doing over the last few months is on what the best Blogger app is for the iPad. Blogging on the iPad is convenient and works great if you're traveling or on the move. Frankly, I hate carrying around a laptop on vacations and have fully adopted my both my iPhone and iPad for any remote work.
That said, there still are some problems with using Blogger mobile apps. The iPad mini is small and compresses your screen size significantly. Additionally, viewing web sites or using online tools becomes more problematic due to the sites switching to mobile modes which can be reduce usability especially for those sites that have been designed for full laptop or desktop work.
Google's Blogger Tool for iOS
I must say I was excited to see that right away Google had created an iOS tool (version 2.1.7.2) for both iPhone and iPad specifically for Blogger that was free in the App Store. I immediately downloaded it and began trying it out.
