The agony of choosing a Macbook?

Question

macbook

Guys! I decide to buy a MacBook Air 13 a1237 in the secondary market, this is the very first air. Everything suits, and condition, and price. I only need it for work. That is, it is important that the office works (2012, I hope, no less), Photoshop is important for simple tasks. And so, to watch TV shows again, well, it would be crowning in Hearthstone when you never cut yourself.
Tell me what I can do with this, what I can not?

Answer 1

This air is weak now. Take a closer look and here's why: a MacBook is a good investment, as this laptop will last you 5-7 years. Taking a laptop now, which has almost served its time, is a waste of money. And even if you somehow miss this laptop today, then tomorrow it won’t be.

Answer 2

Are you considering an alternative to air? 2GB of memory is not serious now

Answer 3

Memory - at least 4 gigs and hard - SSD. It's minimum. If you can upgrade, then ok.

Answer 4

The Air has a poor quality display. Especially in terms of brightness. It is impossible to work in bright offices in summer. We have to look for a darker place, which cannot be said about the Retina of the PRO. And if you want to work outdoors, even more so. Eyra's display is terrible.
You say 2 is not enough, I will say - 4 is also not enough. Considering that the software is progressively eating up memory, in another year 8 will not be enough. Now every second tab in Chrome eats up to 50 MB of memory.
Hearthstone is not a problem. You will fry eggs on aluminum in 15 minutes of hardstone. (any game or photoshop with two dozen layers)
