Though the C521 maybe a small machine, it certainly comes loaded with connectivity options in the form of 6 USB slots, which is surprising keeping in the mid-sized styling of this machine. This is a great feature, as one can easily extend the functionality of the machine with the help of external add-ons. The C521 also has an 11-in-1 card reader, which is a welcome addition keeping in mind the number of memory card formats one has to deal with nowadays. In what is a bad decision, Dell has left out a monitor with this range. Keeping in mind that 17-inch monitors are now under Rs. 9,000, we are just sincerely baffled as to why this has been done especially considering that it is offered as part of the same lineups abroad. The OS that was available on our test machine was Windows XP Media center edition.
A point to note here is that Dell now offers Windows Vista as part of this lineup, which was not available for some strange reason on the test machine we received.
