Very.
In all seriousness if you need a computer for work or other mission-critical applications you can not risk having a HARD CRASH while working in:
DO NOT BUY a MacBook Pro.
I haven't heard as many things about the MacBooks. If you want Apple laptop, get a MacBook. And they have much better WiFi signal reception.
To people saying "well I don't have the problem so is not be universal"...It's impossible to say whether it is or is not universal. But it sure feels like if you haven't seen this yet you're lucky. It's likely a driver issue (thus essentially universal).
I love Apple but their quality has taken a nose-dive. Macs shouldn't have these problems. It's been months, no official word from Apple.
I've been waiting to buy a new 15" MBP for several months. I was so delighted to see that Apple launched the core iX MBPs a few months ago and was planning to buy one to replace my black macbook from 4 years ago (core duo 2.0). However, after this freezing problems have emerged, I have to postpone my plan. The fact is that I really need a reliable laptop to compose my dissertation wherever I go. I also plan to use it to on the day I defend my project. But what if the machine freezes in the middle of my presentation??? My advisor and my committee won't be happy for sure.
It may be worth waiting for the next revision which I, as well as other people, predicted to happen after BTS promotion ends. We might see a new case design. Although this unibody design is still looking sexy and sophisticated but I think it's about time. Historically, MBP received the new case designs approximately every 2 year. MBA and Mac Pro are also overdue for the upgrade. Big big Mac upgrades will happen before Christmas? The freezing problem may be resolved with the new design too...no??
Gosh...I need a new MBP!!!
