ASUS Celeron 1.1 GHz 2GB RAM 15.6" 1366 x 768

Upgraded to Win 7 Pro from home premium, so it is better than new in that sense.

It's cheap and small at 15" works really well for Microsoft software, but my client's proprietary software report generation was too intense for it.  It turned out that I needed a minimum of i5 processor.  So this was used for a month.  I upgraded its twin to 4GB RAM and that speeds it up quite a bit, but not enough for the client's needs.
