I have been extremely happy with the upgrade. Granted, I am far from full time Phototshop artist others are but the new features are incredibly useful to me... and many things work faster or more intuitively for me. As with so many Photoshop upgrades, there will be a lot of mixed feelings - there always is when something changes that is this widely and commonly used. it's like changing the shape of someones paintbrush. Even if the new shape is "better" it isn't what their used to :)
