You are right!

they allow you to switch back.. I know i did in about 5 minutes

Add the webmaster's account. So many extra clicks needed now just to get a web report.

By trying to get so many possible features Google is overcomplicating and making the user interfaces more difficult and time consuming to use.

I'm still not at all keen on the revamped Google Keyword Tool, but I got used to the new-look Adsense after a day or so and quite like it now. Mostly though it does seem to be change just for the sake of change. Not that I imagine Google would spend out on it without having reason to believe that their investment would return to them in multiples one way or another.

I dig the new Adsense layout simply because it shows much more information when I first log in. No extra clicks needed there! I haven't seen the new Analytics layout and honestly didn't even know they revamped it.

The only thing I like in the new Adsense interface is the graph. But I stay in the old interface and only switch to the new to look at the graph, then switch back.

This could be mostly that you just don't like change. Its OK, most people don't and it seems like a lot of people share your opinions. When you've been making money since before Google was even around you learn to just go with the flow. I'm sure you'll get to that point some day as well. Until then, just revert back, takes maybe 5 clicks.

I hated the new adsense interface at first but after a day or two, i got accustomed to it. The graphs are a great new feature. Much more data for me to compare days, weeks and months.

One thing that i missed about the old adsense is that i can view my custom channels within one click after logging in. The new interface takes an extra click or two lol. It's live-able though.

The problem with the new interface is that it doesn't show the most important screen first: The screen which shows you which channels are getting which clicks.
