I should have trusted my instincts. I have always been suspicious of Sony products’ quality-to-pricepoint ratio, but I purchased a Sony Vaio VGN-FE880E notebook, anyway, when my old Dell’s case broke, in a fit of desperation and comparison shopping. Almost immediately, I discovered that the cursor would sometimes jump around randomly, causing unexpected deletions or insertions of text into the wrong part of a document, or even in other windows.
It seems I am not alone: Google search: Vaio cursor jumps.
What a pain. I just hope it holds up long enough to see me through graduation and starting work.
