The first thing to note is that, with minor variations, they all tend to be 'me too' when it comes to specification. Whether it is HP, Lenovo, Acer, Asus or whoever (and there aren't many 'whoevers' these days), it is always a low end Intel processor, 2GB RAM, 32GB storage, a low resolution 1368x768 screen, running Windows 10. The specification is thus very modest and there's a reason for this: Microsoft's are giving Windows 10 for free to manufacturers provided the hardware doesn't exceed a certain level (these laptops/netbooks are designed to compete with Google Chromebooks, which have similar modest specifications).
Although 2GB of RAM is not very much, it is sufficient to run Windows 10 and one, maybe two, programs or apps at the same time. More limiting is the amount of storage; although it is described as 32GB, in reality Windows takes up a chunk of that plus some is partitioned off and holds the recovery image. Consequently, the amount of real storage that you can actually use is likely to be between 8GB - 15GB. These laptops do not use conventional drives, rather the 32GB storage consists of a SSD chip soldered to the motherboard and it cannot be upgraded or replaced. The only way to expand storage is by adding a microSD card (or SD card on some machines); fortunately, a 64GB microSD can be picked up for around £15-£20. You should buy a quality branded one that states its performance (e.g. 25MB/sec or whatever) as low cost ones tend to be very slow.
You might also want to look at the anti-virus solution. Some models are supplied with an anti-virus program (e.g. McAfee) and they can be very slow. Windows 10 already includes a built-in security program in the form of Windows Defender, so you may prefer to use it.
