The Google homepage fills my heart with joy.
Having experienced a multitude of problems with home internet in my adult life (mainly thanks to the shoddiness of NTL's service), I've spent a lot of time testing the connection by pressing Alt+Home to bring up my browser homepage, which is, of course, www.google.co.uk. The "page not found" signals disappointment and the need for further work. The Google homepage equals success and progression.
Even now, with my internet troubles over (at least until I have another go at setting up wireless), the sight of those primary colours on that big white background is dear to mine eyes; I am one of Ivan Petrovich Pavlov's puppies, with Google as my bell.
