1. The short positive comment: "This looks AMAZING!"
2. The rip off accusation: "This looks like Windows 7"
Of course the first one is okay. It's always nice with a pat on the back, but this type of "feedback" isn't really useful.
The second one is the one that annoys me. Although I see the similarity, and why Canonical would want to avoid such a comparison, this idea came long before Windows 7 received it's boot screen. During the Hardy cycle I came across a U-splash suggestion on the artwork wiki. The idea is little different from what I came up with, but this is what the concept looks like:

I really liked this concept and quickly created a mockup of my own version of the idea.

As you can see from the date (Feb 11 2008) on Ubuntu-art.org, where this is posted, this is again long before Windows 7 ever was released to the public. Perhaps the Microsoft designers have been seeking inspiration in the Ubuntu community ;-) Know what I mean? Nudge nudge, wink wink.
Today LanHikari90 posted this comment on my 4th animated boot splash idea:
Really nice. I wish, it would be the official boot screen.
But sadly it is just a rip-off of the Windows 7 bootscreen. And to all these guys who say it isn't: It obviously is!
I've considered disabling the comments or even removing the videos, but every now and then someone will write something worth reading.
