Had this happen last year. Came home late at night on Christmas 2011 to a broken basement window and saw that all my electronics had been stolen - TV, laptop, desktop, game system, etc. While it was certainly pretty frustrating (especially dealing with the police (hint: don't expect much) and insurance company), eventually I realized that it was actually a good opportunity to rebuild my tech collection from scratch.
In other words, think about what devices you didn't use much, and how to replace that functionality with other things you have. For me, this was:
- an early 40" LCD ($1200 circa 2007). It was 1080p, but it was a monster to move anywhere and too small to make watching HD content worthwhile when sitting across the room. Still, it worked fine - I wasn't going to go buy another one. I also don't watch much TV to begin with, so it went days without being turned on. So, I replaced it with an Epson HD projector ($800). Sure, the lamp life is less, but I don't use it more than a few hours/week anyway.
- a Blu-ray player (bought in 2008 for $160) replaced with a PS3 ($200 on eBay).
- an Apple time capsule ($300) replaced with FreeNAS (in virtual sandbox) on desktop computer (free, since I was replacing the desktop anyway).
