This beast can run a Norton Scan, a backup and heavy-duty Ancestry downloads all at once and not bat an eye.  [Ed Note:  That's right, don't run scans and backups together.  Scan first then backup.  But the computer can do it, just fine.]One thing on mine:  the power cord attachment is squirrelly, so I expect I'll have to get a power supply some day, but so far it just works.
