Hey @Siddhartha...
Please grow up!!!
How can you expect Linux to be like stuck up Windows???
Remember problems in Windows are auto-created...
But in Linux, it is user-created...

In Linux this is called Masking... Wherein you cannot even view the number of letters being typed in... More secure... Please type as usual and log in...

How can you possibly loose faith in Ubuntu in a matter of just 14 min.? Please wait for more seasoned users like @pradeep and @GNUrag to answer... I can give you answers to those questions that can be answered by lesser mortals...

Please mention wat ver. of Ubuntu and yr sys config. for more detailed answers...
And finally... Please wait...
If you have Impatience, It is like Windows crashing every now and then

Of course I am not into Windows bashing.. But I installed both Ubuntu and KUbuntu and both worked fine until I myself crashed them out..

No probs then ... So it might be someting to do with your config. Please give more details...
