can we know a brand please and 8 GB SSD? that wont hold even the OS
It's used as a cache drive, a lot of laptops do this. Basically it's a small SSD to hold the most frequently used files to speed up a little, but the actual data is still stored on the HDD. It's no error in the specification, just a type of technology I assume you're not very familiar with.
For the OP:
I would agree with the others though, a desktop will indeed give you more performance for your money. Laptops are nice because they're portable, but the biggest downside is generally that if you want something that works alright, you'll be paying a lot more than you would for an equivalent desktop. Also portability, in my opinion, isn't actually that big actually since high-performance laptops tend to pack a lot of hardware and thus be quite bulky and heavy, so sure you can move it around but it'll weigh a ton.
Myself I have a desktop and just a simpler laptop, anything that requires a strong computer I do on my desktop and the laptop I reserve for general carrying around and browsing stuff, it also weighs almost nothing!
