Bit of a splurge really but I rarely replace things until they're completely ruined and it's easier for me to buy things back here in the UK rather than in Saudi.
Firstly - I have two computer setups for my two homes, 1 Gaming PC in the UK setup in a bedroom and 1 Gaming/Media Laptop in Saudi setup in the living room on a 55in TV and both needed new Keyboard and Mouse combo's. I went with the Logitech G703 mouse for both (using it wired in Stoke and wireless in Saudi), a Logitech G413 wired mechanical KB for Stoke and a Logitech G613 wireless mechanical KB for Saudi where I sit upto 6ft away from the Laptop so don't want a wired setup.
I'd been using cheap no-name brand £20-30 combo pack ones for as a long as I can remember and so I decided to treat myself for Christmas and get mechanical ones and already the amount of spelling mistakes I usually make is going down as I find the more "positive" keys help me massively with my pigs boobs for fingers.
Secondly - I needed to replace my entire bedding system. I wanted to replace my mattress as I think it's been at least 25 years since I bought it and it's so worn out it uncomfortable now so I decided to go with one of these new "expanding foam" type ones from Nectar after reading a bunch of positive reviews, rather than a more traditional "pocket spring" like my current one. I don't think I'll get the same life span out of the new one but the huge comfort increase should offset any longevity issues I'll have. Plus I'm replacing the duvet, sheets, covers & pillows etc with some nice Egyptian cotton ones rather than the "£10 from Tesco's" type ones I've currently got.
