I sold an early 2010 13 inch MBP 2.53GHz for $800.00. I only paid $1400 for it. I'm trying to sell a Sony AW 18.4 inch with Full HD RGB/LED, 1280GB, Blu-Ray... the works, for 1K. I paid about $2500 for that. Not even one response for Sony AW.
I suppose the AW is a niche, but still. I would have expected at least one response for an offer. This thing has a better screen then 99% of the notebooks available.
