I am using Inspiron 1525 for last 8 years. For the initial 5 years I have not faced any major software or hardware problems. Keyboard and other accessories are good . Dell Support service is available for software updates and Hardware replacements for first year. I have upgraded latest windows and other softwares . Laptop is compatible with all these upgrades. Battery Backup is more than 3 hours initially but gradually reduced to just more than 2 hours now. Battery overheats sometimes. I am overusing it with replacing keyboard and battery only last year. I had brought this Laptop at 40000 rs with more advanced software and hardwares available at that time( Somewhere around 2009) . Now days, This series of Laptops may be available at less price with most upgraded versions. Battery overheating problem may have been solved in latest models and battery backup is enhanced considerably. But this series Laptop has retained its versatility and adaptability.
