Of course, laptop wins in several aspects.

• Typing or data entry is more difficult and slower with a pda compared with a larger keyboard for a laptop.
• The specs are more powerful .
• The processors , memory and storage are much better in a laptop enabling you to work with greater efficiency and speed. 
• It is easier to view your work on a much larger screen on a laptop.
• You can watch DVD movies, do video editing
• Even laptops are fighting off this new competition by becoming smaller and lighter.
• Lastly, you can do slideshow presentation with a laptop.

So, you need to weigh cost and benefits of both laptops and PDA. For day to day activities a PDA should work just fine!

Media Type: Since PS3 is owned by Sony and BLUray is Sony’s next high definition storage medium, PS3 games will be stored on BLUray discs which hold approximately 54 gigs. The Xbox 360 games will be stored on Double Layer DVDs which store 9 gigs. Obviously BLUray discs can store a lot more data, but at current stage of game development, any game developed will fit just as well on 9 gig DVDs, so this is not a major factor but one that may come into play later on.

Games: When considering games, you have to look at XBOX and PS2. The XBOX is very popular in US and has a few great franchise games such as Halo, but PS2 has an international reach and several popular game franchises such as Gran Tourismo that XBOX has yet to beat. The XBOX 360 will need to appeal to foreign game developers and consumers to compete with PS3. Only time will which console will have quality of games which all of us are been expecting

Controllers: The controllers on two systems retain basic shape from original systems with some modifications. The PS3 controller has most dramatic change; it has a streamline shape that looks more like a stealth airplane than a game controller. The XBOX controller is basically same shape as previous system with a different color scheme. From pictures released, it seems XBOX controller will be more comfortable and natural to use. The PS3 controller looks like it would just slip out of your hand but we will not know how controllers feel during actual gameplay until we get our hands on them.
