64bit computing is not essential to me at this point, however, it is inevitable to the industry. I imagine it will be essential to me at some point. Currently, a days work will include open windows for Word develop (e.g. System Manual; include documents, TOC, Index), AutoCAD or Solidworks (e.g. engineered drawings, rendering), Internet (search for resources), email (to keep in touch), and then theres that source development thing. (Sometimes i have more windows open than AltTab can display (at one time); dual monitors is a must. Though I have to admit, i seldom c "idle time" suffering in Task Manager, but sometimes pagination p's me off. On the other side, I embrass technology but i don't like to feel foolish about such; Vista makes me feel foolish. What the !@#$%!@ do i need with all the sparkle, glitter, and shimmer of Vista's animations; nada. I don't how many time i'v created directories n the wrong tree because Vista Explorer doesn't navigate quite the same; not to mention that it's much harder to c where the !~@#$ u r at with the transparencies and pastels (I'm aware that this can be disabled). And i'd rather take my "Once Every Three Year" security breach rather than b asked "if i authorized this event" for every !@#$ thing that i do. On a lighter note, I hate the mouse. I never use it unless i have to; i have a trackpoint keyboard so my hands don't have to be wondering around for that stupid mouse thing. With that said, Vista took away the END key functionality in Solitare (and other keys in other places). Actually, it was Solitare that broke the camel's back for me. Vista Solitare much slower than XP's rendition and it's more cumbersome to play; that makes me feel foolish (after i spent over $5k on 64bit stuff -i don't want to b wasting my time when i'm wasting my time). Enough said, ... I'm done with it (for now).
