This is the inherent problem with Internet forums. The concentration of people who have issues is very high because the people who don't have issues typically aren't seeking help from Internet forums. As a result, people think small issues are rampant.
Add in the fact that forum posters in general are insanely picky and paranoid about the product they are talking about.
It sounds completely sensationalized and blow out of proportion.
Exactly this - it always amazes me when people don't seem to get that. I think it even has a name - negativity bias.
With regards the new MB - I am looking at replacing an aging MBP from 2008, and had always assumed I would get the 15" rMBP. But thinking about it, back in 08 it was my main machine for work. But now I have a 27" iMac, and actually portability is much more of an issue. A lighter more portable laptop that is never going to be needed for much grunt work makes me think the 15 MBP would be overkill.
I've had a quick play on the new MB now and it is stunning - so much so that I'm now seriously considering it as the best option. If its mainly going to be used as a secondary work machine for me to take out to meetings with clients (I do web design), maybe let me have some time out of the office (I work from home) over a coffee and getting bit of light work done, and general email / web surfing etc by my wife at home, then it would probably be fine.
Sure - a big part of my head still says to go for the 13" rMBP, but if:
1. Its not going to be a main machine, so will rarely be called upon for much heavy grunt work
2. I would mostly use it to take out to meetings, often in London so a bit of a trek away
3. Around the house it will mainly get used for general email / internet, bit of Word / Excel.
Then the MB would absolutely fit the bill - its probably too easy to get hung up on specs rather than take a step back and think what its purpose is.
And who is to say that weight and portability aren't specs anyway? Just as someone could say that its a no brainer to buy the MBP because it is more powerful, someone else could equally say that its a no brainer to buy the MB because it is so much more portable, especially if it is powerful enough to boot.
So if you get extra power you don't need, but lose portability, then that's a net loss.
Just as sacrificing power you do need, for portability you don't value would be a net loss.
Or something - and yes, I realise I'm probably a little guilty of trying to convince myself that the new MB is worth a serious look.
