Desktop or laptop

My pc had broken down several times on me, I had lost hope on it…
as im thinking to get a new, and I’m bound with decisions; desktop or laptop.
Definitely desktop is much cheaper n more power, easy to upgrade too… but laptop is a trend now… is getting much affordable plus its portability makes its plus point. And who will often upgrade their own pc… beside of just getting a new one instead.
I was amazed by lot of choices in the current market, must be cos im veri outdated!!... wow… laptops come in lots of colours n surfaces, glossy, leather etc. im impressed by the Sony Vaivo series n Asus ones… come in different themes… fast car Lamborghini, some even come with scents.. Like Fujitsu… There are laptops with fingerprint security... wow... cool, like secret agent. In fact, Asus come in a new technology (Eee pc), a very small cute desktop (which look more like portable vcd player); is cheap… but its lacking pt is no optical drive so u need a portable disc player along.
Now from what I been gather information.
Criteria im looking for; Intel Centrino 2 Processor Technology - Intel Core 2 Duo (with at least 2 GHz), a considerable display screen 14” onwards (as I dun wan to strain my eyes too much) that comes with a much better keyboard and with optical drive, had a webcam 1.3p above, must be under 2kg, not a bulky power adapter (preferably able to use with overseas power supply too), reasonable 2/3 DDR-2 SDRAM, a connsiderable hard disk abt 250GB, safety lock maybe and international warranty etc. And the list may go on... like example an unique colour perphas
