I dont think the problem with the people you referenced in the OP is that they are apple fan bois I think they are just d*cks.
I am a huge apple fan now - I check macrumors.com every morning before facebook
I wouldnt queue overnight to get a product as that just doesn't fit into my lifestyle but I will order the iPhone 5 on the earliest day that I am able. I actually downloaded Lion as soon as it was available and iOS 4 at 5AM on the day it was out...
I am a bit over the anti Apple rants though - people constantly asserting that they aren't the best product and that xyz product is now much better than abc apple product.
People should just buy what they think fits their needs - if people ask my advice I will obviously suggest an apple product. I will also honestly counter all the nay saying (such as "the iPad hasn't got a USB slot so it is rubbish").
I don't see me moving away from apple products as the cross platform harmonisation just works for me now and when iCloud is out it will be even better (if I can find a job with international travel that allows me bring my phone and not force me to have a company BB).
For me the biggest problem with the iPhone is international roaming - the BBs I have had have cheap access to data overseas - with the iPhone I have to get a local sim and that is a hassle for very short trips.
