Yep.

Mhmm. I got a 'prebuilt' (though partially customisable) Sony laptop rather than fully customising my own, as having a Sony store round the corner for when things go wrong is very convenient. The downside is that there was no Windows 7 option for the OS - and sure, I could put 7 on there myself, but 8 isn't nearly enough of a hassle to be worth that. It gets way more hatred than is deserved.
