I have monitors and peripherals in my home office and at my work office, so I only have to transport the computer. I am looking at getting three of the ASUS portable monitors that are only 1/2" thick for when I travel so I can put everything in a reasonably sized case.
I really like having everything I do on one computer (not a desktop and separate laptop), and I don't care for laptops' keyboards and small screens. I can also make a little more powerful computer for the price building a desktop. A notebook would be convenient though.
