My 7-year-old Asus Z96J is still humming along (with its beautiful 15.4" 1680x1050 screen). Shame it has a PATA hard drive connection, or else I'd throw in a SSD and use it until it croaked. Well, the battery is also shot, and so is the DVD drive, but it surfs and web and accepts SDHC cards.
My 4-year-old Asus EEE 1000HE recent got a SSD installed, and it's also performing well. I will probably install Window 8 RTM on it soon.
My next computer (in a few months) will probably be the Asus Zenbook UX31A-DB51, unless something with better specs comes out. I will also buy Mrs. Swede an Asus Ultrabook should they release a new one with a 1600x900 screen.
