Along with the lunch of the new black bar top navigation on Google, Google launched a new top bar for mobile users. I assume people are just so upset over the top black bar on Google.com on their desktop that they don't have that much time to complain about the new mobile top bar.
Here is a picture of it:
I am a bit shocked that Google has made the mobile top bar more graphically intensive than the desktop top bar.
It not only takes up more space that the desktop version, which is bad since mobile devices have much less screen real estate but it also takes up more bytes in size because of the graphic nature of the top bar.
That being said, I am sure Google does everything to minimize the time it takes to download the top bar on a smart phone. Plus, Google auto scrolls the top bar down beneath the fold so you do not see it after the page loads but it is still seems excessive.
There is a thread at Google Web Search Help with some complaints. One searcher said:
I agree. At least give us the option of disabling the auto-dropdown. I, too, have been errantly hitting the icons when they drop down. It is VERY annoying.
