I have recently purchased a new Laptop and that is of Dell Vostro and also it is the best that i have till now, The other thing here is that it has it has all the latest configuration in it but no bluetooth. Bluetooth is the device which enables us to share data or files between two devices with out connecting or we can say that without wired connections. The other thing here is that Since i am not having bluetooth in the laptop that is the reason why i purchased it but i don't now hoe to use it . I have purchased a USB bluetooth device named bluetooth dongle. And i am using win 7 as my operating system.
