I have to buy a new laptop from the 4 available options. Kindly advise which is the best.

The available options are below:

1) HP g004AU Ultrabook 15.6 inch (39.62 cm)

2) Hp 15 d008tu Standard Laptop, 15.6 inch

3) HP Pavilion 15-r036TU Standard Laptop 15.6 inch (39.6 cm), Sparkling Black

4) Lenovo Flex 10 59404493 Standard Laptop, 10.1 inch (25.6 cm)

Please note it has to be one of the 4 above as i have to buy in from reliance digital store with the gift cards i have and these are the only 4 options available in the 20-26 K range.

Kindly suggest which one would be the best and why.

Lenovo Flex 10 all the way. Almost all HP laptops have overheating issues. Lenovo is a much more reliable company and I know that the Flex 10 will use windows 8 to it's full potential as the laptop's form factor is tailor-made for the OS.

Lenovo Flex 10 59404493 Standard Laptop, 10.1 inch (25.6 cm) is the best laptop.

Lenovo Flex 10 59404493 Standard Laptop

Lenovo Flex 10 59404493 Standard Laptop, 10.1 inch (25.6 cm) is the best. I'm looking into buying an HP Pavilion, but the big difference is you could get a longer life out of a Lenovo or ASUS.
