1) Depends on what you call a 'wicked spending spree'. I've spent just a little over $100 since my birthday on DVD box sets... that aside, my last serious spending spree was when I dropped around $200 on a Japanese PS2 and a copy of Mushihimesama... It would have been much higher had I not got such a sweet deal on Mushi. Even used copies of that game go for over $160 on eBay.

2) I originally named my computer Yotsuba, but when she got sick and died, I sent her corpse in for repairs, and I left her soul in an external hard drive, where she resides now. When I received my repaired computer, I named it Matsuri. Anyway... *checks dxdiag*
