There are several models which you can get that will feel like a massive upgrade (and hardly a downgrade especially if you are buying a new laptop after ten years).
But then some things are important to know. What is the screen size of your current 2011 MacBook Pro? Is it the 13-inch, the 15-inch or the 17-inch? And what you really like on your MacBook that you would feel a huge downgrade if you lost? The keyboard? The trackpad? The screen size? The feel of aluminum touching your hands?
The only reason I'm looking into a computer right now at all is because my mbp isn't working.
With that said.. It is a 15" mbp, late 2011, 8,2, A1286, 2.4ghz i7, with 16gb ram, and an ssd upgrade (that I hadn't been, but was soon going to use).
I want: a 15" screen (I'd maybe settle for something in the 14" range). A usable keyboard with well placed, "quality"(?) keys. A trackpad that works and performs as good as the one on the mbp, and has gestures like it. A quality screen. Decent resolution - no less than whatever my mbp is (1680x ...1050? I can't remember. I opted for the "high resolution" model when I bought it though).
It's the first and only laptop I've owned. I'm using an acer aspire right now (not mine) and it is the worst computer I've ever had to use in my entire life. It's a piece, of, garbage. I have to smash my fingers down into the keys; plastic-ey, flex-ey trash. Poorly spaced and arranged keys, crammed, always hitting caps lock by accident. The trackpad is absolute garbage as well, and the placement is stupid; one constantly touches it with their palm below their thumb and looses whole bits of text or performs some unintended action or other. The screen is one that makes the user feel as though it was designed to destroy their eye sight; pale, washed out, low resolution. The speakers; trash, they crackle and have weak volume.
That's just the user experience with the "ergonomics" or "hardware".
The performance. I don't even want to... it's the worst. Right click a file/folder on the desktop and it shows an hourglass and takes upwards of 30 seconds to show the right click menu. It's capable of nothing.
It's like a toy almost, one you'd let a toddler with applesauce and stuff all over them play with for fun.
So, that's how bad it can be - haha. Rant over.
So, while one reply mentioned that my usage needs are "utterly mundane", this acer cannot do half of them, and struggles to do the rest to the point you wan't to literally smash it.
I duno if that helps at all.
Thank you.
