I wouldn't recommend this laptop for audio.
It's a dual core 1.8GHz Celeron, with a 5,400rpm HD and 4GB of RAM.
Consider that Windows 7 is ram heavy itself and I uses like 2GB of RAM already. So... one large Omnisphere patch would knock out your RAM right there. And if it didn't... I'm sure the 2nd patch would finish it off
. That just means that you wouldn't be able to load a ton of patches. I think 6GB of RAM is the bare bare minimum you'd want... but 8GB is the lowest I'd ever recommend for current audio production w/ Omnisphere and VSTs like that.
The processor would handle a couple of VSTs... but nothing significant. I'd imagine being able to load an Omnisphere instance, a Nexus, a Sylenth, maybe a few stock plugins and that's it. Just a ball park guess. When I was on a 1.8ghz Single Core Celeron.. I could load approx 4-5 VST instruments of that caliber, and maybe an Amplitube if I was lucky. So... this computer would do a little better but not by much. I'm surprised they still even sell 1.8ghz Celeron's honestly, given all the advancements. I think they're just trying to make money on people who need a cheap computer that will be excellent for web surfing, music playback (not production), and MS Office use.
If you want a laptop to produce, look for at bare minimum a laptop with a decent clocked i5, 7200rpm HD (or swap it yourself with an SSD), and 8GB of ram. That should be something you can work on. I haven't price checked but I'd assume you could find one for around the $600+ mark. Load up Windows 8.1 on it. It's a lighter OS and I find it great for audio. Just as good, or maybe better than Win 7
