I am a fan of the Lenovo Thinkpad series of laptops and I have started ising the Thinkpad E450 recently in our office.
It is firstly a very sturdy construction like all thinkpads are. This particular model is powered by the 5th generation intel core i3, with 4 Gb of Ram and 500Gb of hard disk space. This is a good enough configuration to get any of my office task done with ease!
The laptop looks and feels very premium and the best thing I like is the keyboard and trackpad they are very responsive and accurate!
The screen is half HD screen but is very good in terms of colour saturation and brightness.
This model has no DvD writer. The battery life I get out of this is approximately 4 hours which is pretty decent. The laptop is pretty silebt, light weight and has no heating or hanging issues! The USB ports are fast and convenient. The one downside of this Laptop is that is come by default with Dos installed and windows must be installed by the end user. It is for this reason that the laptop retails at a lower price of approx 33000. The warranty is one year and the after sales service network of Lenovo India is pretty good. I am a satisfied user of this Thinkpad and this model gets a recommendation from me! Do check out the actual pic of my laptop attached hereby!
