HP has transferred the materials, the quality requirements and the stability of the grown up EliteBook siblings into the thin format, the concessions are acceptable. Because of that the weight is slightly higher compared to consumer ultrabooks. The base unit is not completely torsion-free as with an aluminum unibody. By grasping the right and left sides with both hands the base can be limitedly twisted. Nevertheless the chassis reaches a very good stability level when measured against the excellent maintenance capabilities.  Noticeable with the Folio 9480 is its almost complete slight rubber coating. This soft-touch surface enables a good grip and prevents fingerprints.
