Cheers looked at reviews, said that performance on day to day like Google chrome tabs etc, lags and suffers. That would get on my mum's nerves as she uses down stairs
The issue with any budget laptop is that, if you don't take good care of the file system and applications, it'll become sluggish and a pain to use very quickly. That'll happen regardless of the laptop brand you choose. If you look at laptops with similar specifications, you'll likely see the similar reviews pop up for them.
I'm heading out right now so I can't provide specific models (I will later this evening), but my current advice is that you should aim for at least 8GB of RAM. Chrome is very RAM-heavy and if you have a few tabs open, as well as watching a film and using day-to-day applications such as email, 4GB will start to be a bit limiting.
