3 years on laptops now. My frst was a Toshiba which was *****, then a PowerBook and now a MacBook.
I've a nice little set up with a 19" external monitor and hd and a bluetooth keyboard and mouse and a tablet (which I rarely use) and a load of wires running to a usb hub. I've even forgotten the uses for some of the wires. I have that set up in Dublin, and then I just close up shop and go portable for college and going home at the weekend.
It suits me perfectly, and at present I see no need for a desktop (maybe I'll get one when I finish college, or maybe not)
