My personal laptop is a Lenovo T400 with Ubuntu Linux, it also has Vista which I plan to upgrade to Windows 7 (but I use Windows so infrequently that I just haven't gotten around to it).
My personal desktop is a system I put together myself, build around a Gigabyte GA-K8NXP-SLI motherboard, running Debian Linux.
At work I use a mid-2009 MacBook Pro with a 2.66Ghz CPU running Mac OS X 10.6, and a few Windows XP, and Windows Server 2003 virtual machines for testing code and other stuff.
Sony Ericsson C902 phone, which I'd like to replace with an Android phone (I'd prefer something on the small size). But, I'm reluctant to pay extra for the data plans.
I've also an old Sparc station under my desk at work that I'd like to get running, and some Linux and Windows 2003 servers that I manage.
