Hewlett Packard (HP) (NYSE: HPQ

Quite popular among domestic consumers-Competitive pricing, good sales and service network, lots of features and occasional promo offers
Pros:

1. Lots of value added features: Like Remote Control, Fingerprint recognition, Webcam etc, not available in most of the competition models of similar configuration
2. HP liveperson chat is quite useful (Available only during US hours-You can chat with a sales executive who will answer your queries related to HP products and services
3. HP promoted lightscribe technology available in most of the units (Read this post for more on lightscribe technology)
4. Decent sales and service network
5. HP imprints can give good look to your unit (it is a sticker kind of thing with attractive images/scenery etc which you can stick to back of monitor)
6. Excellent collection of Accessories

Cons:

1. Latest processors are not incorporated.
2. No option to make any changes in the specifications
3. Not so robust compared to Dell and Sony.
4. Very few models in high end segment.
5. I am not happy with HP's recovery manager software-Read this post for details
6. HP gift redemption process is a pain. You need to send a DD for Rs 500 to a delhi office along with bill copy, product sticker and many other things and wait for 2-3 months. Why not give the gift along with notebook?
