If this was your only PC for school, stick with Windows. As to the other comics, be sure you have an acceptable app for the comics. And browsing the web is a little less capable than your Windows versions. You know that going it.
As a second PC, android works for me.
I already decided that I am going to buy a Lenovo Yoga 2 10" tablet.
However, I don't know which OS should I choose. The tablet comes with Windows 8.1 (costs more) or Android 4.4. I am going to use the tablet mainly for reading comics and browsing the web, but occasionally also for writing things down in school.
Which OS should i choose? Thanks
