MS
I do bow to MS, they make a poor, buggy OS that has sold well as there is no viable alternative for many people - it's not the best OS at all, but then again it's quite specific really, if you want to run SQL based apps it probably is, if you want a straightforward easy to use OS that works well, buy OS X if you like fiddling with stuff but still like a solid OS buy Linux... buy for what suits.
I work with MS everyday, i also work with Apple everyday - and the Apple products are, generally speaking, far better than the MS ones.
The iPod is the best mp3 player, it's so incredibly easy to use, it has excellent quality DAC's on board, they have clever add on features - iPod Touch and Nano with Nike+ for instance. If you don't agree that's fair enough, but i'd love to see what is better? Sure it is quite linked to iTunes which isn't everyones cup of tea and the standard headphones are shite.... but i like iTunes and have my own headphones so not an issue.
Best browser - tough one, the fact they've never claimed that is probably immaterial to you? The claimed the fastest and i believe it is still... but based on what - who knows, or cares. I use it because i like it, i also Firefox because i like it, and Camino, and Lynx, and IE5, 5.5, 6 and 7.... as a web developer you have to you see and Safari is one of the most consistent products when it comes to adhering to web standards, firefox claims to be and whilst it's better than IE it's not as good as Safari.
As for Best Laptop - nothing touches the Macbooks for performance, style etc... yes you can buy cheaper, lighter, faster etc, but in one package... it is the best.
Thinnest laptop - argue all you like it is - not relevant in my life but it is the thinnest.
Greenest - again, it is... no other mainstream laptop is as eco-friendly based mostly on the fact that the vast majority are made of plastic!
