I use a desktop and if I can afford it someday I will buy a laptop, they are much more mobile than desktops.

I can understand wanting a laptop as a second computer to take on a trip or as an auxiliary to a desktop, but given the issues of battery charging, the wireless internet security issues, and the differences in CPU performance, why on Earth would you want to depend on a laptop as your main computer?

When I'm at home, I use my desktop over anything. I don't care to use my laptop that much, simply because its not comfortable to use for long periods of time. If I need internet on the go, I typically use my phone. Usually, the only time the laptop gets used it when I'm traveling.

I just upgraded my laptop and after a little research went with a Black Macbook. It's a great machine. Easy connectivity, rugged and small enough. Reasonably priced and you can find great deals on slightly used ones.
Also joined MobileMe for synchronicity between my iMac and iPhone. This allows me to ensure my contacts, emails and schedules are constantly up to date.
I am using my desktop a lot less at home because its so easy just to sit on the couch, deck, bed.... and surf

Good luck.

PS I looked at the Airbook but I think the compromise is too great just to lose a few pounds and part of an inch.

Good to hear. I have been thinking about doing the same thing, but afraid to make the change after many, many years of PC use.

Don't worry Jeff, Apple will be gentle with you if its your first time!

Desktops are more reliable in my view, and the easy upgradability too, but yeah, I have a laptop too which I use when I am out and on the move. But first choice is desktops.

I just have a desktop. I am planning to buy a laptop shortly as it has become a trend in my locality.

I do not know why but I prefer laptop. I consider them much more comfortable because I like to use the Internet in all rooms and for the outside. I have two HP laptops.
