The EAs look very similar to CW and i think they are meant to replace CW series. Based on the reviews at notebookcheck i would still stick to CW if i have to choose. Speaker wise, i use external speakers so i don't really care.

Does anyone know whether Sony warranty covers hard disk bad sectors? HD Tune highlighted "Reallocated Sector Count" and got "4" under Data, so obviously the HDD is having few bad sectors, but not severe. Since my warranty is still valid for a few months so i'm thinking if it's possible for them to replace my hard disk.
