A defective product collection and performance weaknesses

I bought this laptop mi after I already more than a week ago had him in the cart and then got seen at checkout that 39 shipping (to Austria) will be due.
So I have all quickly aborted and the laptop continues to be left in the basket.
After I then saw about three days later, with shining eyes, that the laptop was more favorable (about 30 approx) and FBA (so yes also free shipping to Austria), I have not looked long, because I already in advance some read tests and opinions have and have it equally ordered and paid for.
Get got it two days after the order, this time kudos to the seller.

But then I saw that there is another laptop, did indeed get the correct, I ordered, but that was not the Lenovo Z50-75, I'd lie in basket.
Since this article totally different notebooks are listed under 'color', my wish notebook was then sold out and it was me automatically 'Other Colors' appears Amazon.

I was disappointed, but now but my short impression:
The design of the Lenovo G-50-30! I really like, it is very thin and light, and the workmanship is top, the edges particularly forward quite "edgy" are a little rounder would there have been a better solution. The keyboard springs back easily, but that's not bad (at least for me).
The Windows 7 Professional is installed properly and activated, drivers are all installed and available before the first turn.
The performance is for my needs but clearly too low, and I need it only for Office, Download, Internet and very minimal 'Gaming'.
But my Ancient, but new patch Dell boots faster from 2007 and is nearly the same rate, I can not quite understand. I also do not understand all of what such a system needs to 8GB of RAM?

Whatever the Seih that was probably partly my fault because I've seen too little, but it borders probably on a nerve that total different models are listed under an Amazon product, and can be selected only under 'COLOR'.

Also on the customer recessions you can not really trust Unfortunately, because there recessions of the laptop, I bought it (Lenovo G 50-30), are mixed from the Lenovo Z50-75, but also from a Acer Aspire E1-531.

Have the Notebook sent back again, and it was really simple and quickly went. For this, a big thank you to Amazon for the excellent service. But since everything went as smoothly but I give 3 stars.
