The speed of their customer support team! They are always available for you no matter what time it may be or where ever they happen upon being online (as long as its not during business hours). There isn't much I dislike about this product but that's because there really aren' any issues from my end - which makes me feel like if anything goes wrong then maybe i'm just using an inferior system? But everything has been great so far other than some minor glitches here &there when upgrading/installing software etc.. It doesn’t take them too loooong though before getting back tot he "main menu screen" wich will tell one exactly how well versed someone actually knows his way round said computer systems setup menus / screens without having all those "dummy letters". This helps out alot since most people don'; know nothing abut computers aside form basic use such things would normally do eg internet browsing emailing facebook.
