sbi atm machine

I have always wondered why these SBI ATM are so slow to work, the touch screen is sluggish, menu and buttons have time lag as you must have noticed when you enter the amount, it appears late on screen and what to say whole machine is lazy. Today in the evening I went to ATM and the gatekeeper was doing something behind the machine and some people were waiting. I asked what happened, is it working? Quick came the reply “yes ofcource but you have to wait for five minutes as there was a power failure and machine will take some time to boot. I kept waiting and screen flashed and I couldn’t believe at what I saw, it was a Pentium 3 ! And the way it counted onboard memory reminded me the days of 386. Now I came to the secret behind its slow working and I was laughing when I saw it loading Windows Xp ! It took almost 3 minutes showing that Xp screen and then again some 5 – 6 minutes loading some software, at last it came alive. Its so costly machine and can’t they throw in a Pentium 4 processor and some more RAM to give it a life? I know these machines don’t require much processing power as needed in fully functional computer but then why it’s slow? I have seen some other bank’s ATM using Windows98, hope it must be little faster.
