I am new here, but I suppose you are what they refer to as an "Apple FanBoi?"
Take a look at the iPhone forums. That's where you'll find the Apple fanboys.
I can easily afford this thing, but if you carefully consider the reviews (not just cherry pick the good bits) and user feedbacks
I did.
AnandTech's review seems to say it's excellent, and indeed, they've given it an Editor's Choice.
The Verge gave it a 9/10.
Engadget says it pushes and redefines the category, with the only drawbacks being its price and the incompatibility with MagSafe 1.
Please carefully consider the reviews, and do not just cherry pick the poor feedback given by people who have spent 5 minutes with it on this forum.
and simply use the thing in the shop (use it as you will use it in real life, not just look at the pretty optimized apps),
I have used it as I will use it IRL... mainly because I own one and have been using it as my main computer for several days now. I honestly have no idea what everyone is on about when they talk about lag and screen burn in.
About the pretty optimized apps... they look nice, but the pixelation in non-optimized applications is nowhere near as bad as people on here say it is.
then it is not such a bad decision to not buy the rmbp just yet. If you want to buy it, then go ahead, but there is no need to bash people for sitting it out for a while due to some obvious drawbacks that have not yet been fixed........
Of course it's not a bad decision to not buy it right now. It's not a limited edition so you can buy one in a few months, and it doesn't give you wings or anything. If it's not right for you, don't get it. Simple as that.
What I'd like you to do is take your own advice and actually go, sit down with an rMBP, and use it for a while. Or better yet, buy one and use it for a week.
Return it if it really doesn't fit your needs, but don't go telling people who actually own these things to spend some real time with the machine. Instead, go do it yourself.
