Not even close to being true. Blu-ray is meant to be watched wherever people want to watch it. I have a better than any Apple display sitting on my desk right now. I've hooked my dedicated blu-ray player up to it as well as an external blu-ray reader connected to my PCs and the picture is downright stunning.
As for audio, as long as you have a good DAC, headphone amp, and a set of Audio Technica, Grado, or Sennheiser headphones (NO BOSE or Sony), you'll be able to hear every fine detail in the audio, just not in surround sound.
Not only that, but some of us like to hook our computers up to our home theater systems. This is where Macs fail, as they don't have HDMI or blu-ray capabilities. I hook my Windows PC up to my home theater system via a single HDMI cable all the time to enjoy videos and games. But I can't do it the same way with my Mac because I need a mess of cables and adapters and I have to run Windows to get support for what I want or need to do.
Proper upscaling will not negatively affect the video quality.
Well, neither one of those is true either. But blu-ray on a laptop is either for the person who travels a lot or has their system hooked up to a nice external display. Plus blu-ray doesn't require a lot of CPU time. Thanks to bitstream decoding in Windows, my original unibody MacBook pushes blu-ray video at around 15% average CPU use. In OS X, thanks to the lack of bitstream decoding of video, H.264 standard definition video and DVD video take about 20-25% CPU time. Blu-ray video in Windows takes less CPU time than standard definition video in OS X.
Funny you say things like that when OS X actually detects a small number of malicious apps itself (built-in minor virus detection) and constantly warns the user about downloadable apps possibly containing malware. Every time I install an app that I've downloaded, OS X warns me it may contain malware.
So OS X is every bit as bad as Windows when it comes to warning the user about malware.
Maybe if Apple put as much time into making the OS stable as they do coming up with warning screens, OS X would be as good as Windows and not years behind?
Well, as far as the new iMacs go, it's nice to see Apple offering a $2,200 system with the same specs as PCs had a year ago. Since they're so far behind the curve, maybe we'll finally get HDMI and blu-ray on Macs at the end of 2011? Seems it takes Apple about two years to finally start offering features that were standard in PCs... two years ago. That means we should see dedicated graphics in 13.3" Macs sometime in 2011! hah!
