Whilst this is an easy to use keyboard and most of the time auto correct gets it right, the spell check feature is just woeful - sometimes it will allow me to type complete garbage words or even simple words that have an obvious typo with without even attempting to correct them. This is completely unacceptable for such a major keyboard app as something developed by Microsoft, and whats worse is I never see any attempt to make patches or improvements from Microsoft, like they just don't care!!
