I finally got a decent sized desk (Nordic Desk 1600 from Officeworks, $169) and mesh-back computer chair (Seatwell Mesh Chair from Coles, $39):
The chair was a real surprise. I wasn’t really expecting quality/comfortable office furniture from a supermarket, but this chair is really nice.
I think it’s about time to upgrade my computer. The last time I upgraded (aside from getting a new monitor) was over six years ago. The system is fine for general web-browsing and productivity work, but pretty slow for development.
