Okay, this is just a personal preference/opinion, so hopefully won't start the sort of arguments that usually result from this topic.
My personal laptop has a dead power supply, and subsequently a dead battery, so I'm watching something on my (touch screen) work machine, while trying to use an iPad to go through my messages.
I have to say that the word and letter targeting on Windows 8 while doing text input/editing, is far superior to iOS. I don't think I've had a single reason to critisise or complain about the Windows device (or even my Windows phone), but I do often complain, and get frustrated with the iPad and my iPod Touch. I also find the spell check and predictive text to be far better on Windows 8 than it's ever been in Word. Hopefully Microsoft will learn from that and apply it to their next versions of Word.
