Since pretty much all mail clients now have a preview mode which displays the top few lines of the email; top posting is actually practical. This is especially important on smart phones and devices with small displays.
Microsoft wins this one first on volume (outlook being the most popular email client) and second by accidentally providing a useful feature.
I still prefer inline replies for detailed technical discussions.
