I need a new computer. I wanted to buy a 27" iMac with a fusion drive. However, these aren't available anywhere in Switzerland for immediate purchase. If I order it from Apple, it takes 8 business days to manufacture and another 14 business days for it to get here, meaning I'll wait about a month for it. So from those who bought one without the fusion drive: just how slow is it? I primarily do office work and heavy-duty photo editing with Lightroom + Photoshop. Very light video editing, no gaming, no coding. I'm used to working with a fully loaded rMBP but don't want to carry it to work anymore everyday - I'm planning on leaving it in the office and getting a new computer at home.
