@humanity: I'm a little confused on this. What stops people from importing? It's a region free console.
By region free you mean the discs right? It'll be region locked if you try and connect to the internet. MS locked people out of games - even if bought digitally - if they included GFWL and lived in a country MS didn't like, so it's not like it's something they wouldn't do.
Asking 'british' people about tea is dumb, cause the only tea people drink here is fairly boring black tea. Usually with way too much milk and sugar. Ask Chinese or Indian people about tea, they know what's up.
They will both make you look like a guy who thinks "HEY I LOOK FUCKING GOOD RIGHT?" so if you're ok with that then go for the... I dunno which actually, I think they both look kinda bad. Also neither are waterproof, so what's the point?
Also you're thinking about spending close to £200 (that's over $300 yo) on a coat that barely serves a purpose as a coat so I'm not sure my words will really get through to you.
You should upgrade those HDDs to Blacks, and probably get a better SSD. I am also not entirely sure you need such ridiculous RAM, especially when it costs £300. You could get cheaper Ram and then have a better CPU, and SSD. I don't honestly know whether the speed the RAM is running affects CAD work, but 32 gb of 1600mhz is easily £200 less. That's almost another 280.
