Very mixed feelings
I don't use the webapps all that often but in all honesty I do admire them, even though they're limited when compared to the desktop apps.
As said; mixed feelings. I admire the stuff they did and the enhancements they implemented. Most of all we shouldn't forget that this is basically a free service which I also admire.
But having tried the new Word (in both SeaMonkey /and/ "as intended" in MSIE 9) I have very mixed feelings. I don't like the ALL CAPS TABS. Its too "loud", it draws my attention due to the ALL CAPS while it shouldn't do that IMO because "Low Caps" automatically make you pay a little more attention (IMO) to what you're doing.
I have Word open, I want to add stuff so I select: "Invoegen" ('Insert', my Word is localized). The '3d' and gradient (semi-transparent) look is enough to achieve the 'tabbed look'.
I have Word webapp open and in general the same applies. My backstage 'File' is blue and gradient, and the 'Insert' tab looks clean and neat. "Insert".
This new setup is too screaming to my liking. HOME INSERT PAGE LAYOUT VIEW.
Give me a break here!
As said; I don't use the webapps that often but sporadically. If this gets through then I'm pretty certain that I won't use the webapps ever again. The interface is flat, the tabs are SCREAMING and maybe its just me but the flat colour interface is plain out annoying to look at.
Current webapps: The paste icon is a yellow clipboard with a paper in front, selected options are in yellow while my overall theme is in blue (my file backstage tab is blue gradient). Because of the different colour its easy to spot the current selections.
New webapps: /Everything/ is in blue. Apart from the paste icon which all of a sudden looks flat and lame. But options such as alignment, font selection, its all blueish. The same colour as the overall theme which makes it /very/ easy to overlook because it all looks the same.
As such; mixed feelings. I admire the effort but I dislike the current interface quite heavily. Its too noisy.
