I got Acer Aspire about 7 to 8 years back for around 25, 000 rs with windows vista installed in it. It was my first laptop. it is working great.
Till now I didnt regret buying it. with that I got 2 installation cd for restoring when needed. I have installed windows 7, 8 and now its running dual boot with windows 10 & 7.
I did many software experiments on it. It survived all the time and most importantly it installs all drives automatically when ever windows is installed newly.
Internal HDD is SATA which is there in many acer laptops which is useful in partitioning drive or combining them. Till now all parts are functioning well like CD rom, 3 USB ports, Hdmi etc. I suggest others to go for acer if you want to use it for long run,
