En total, el T550 cumple principalmente con el elevado estándar de la línea T y justifica su precio. Es un portátil business relativamente ligero, robusto y bien construido, aún cuando no facilita el mantenimiento, que convence con su funcionamiento fresco y silencioso. LTE lo hace más flexible que los modelos dependientes de Wi-Fi. El paquete de seguridad es absolutamente satisfactorio, el teclado y el touchpad son de primera, y todos los interfaces que precisa el grupo objetivo están instalados.
Aunque el rendimiento basta con facilidad para los programas estándar del sector empresarial, la frecuencia ralentizada del procdesador deja un regusto amargo. La pantalla TN, que al menos es brillante, no va con el precio. Lo más llamativo del T550 es sin duda su fantástica duración de batería que hará el portátil particularmente interesante para usuarios que tengan que pasar largos periodos lejos del enchufe. Los compradores que precisen algo menos de rendimiento o una mejor pantalla puede en teoría encontrar un vasta selección de modelos T550 que satisfarán estos deseos. Sin embargo, sigue siendo cuestionable cuál acabará llegando a las tiendas.
