I've got a
- Lenovo G700a laptop with Windows 7 and Fedora 15 dual-boot (i3 2310-M, 4GB DDR3, Intel HD3000 and Radeon HD6650 switchable graphics)
- Samsung Galaxy Ace with android 2.3.7 (unofficial cyanogenmod port)
- ASUS EEE Pad Transformer with Android 3.2
- Athlon II X240, 4GB RAM and Windows 7 at home (I use this rarely as now it's most family computer)
- ASUS 1000HE laptop running Fedora, with a broken screen (serves as a server for SVN and other stuff)

In the future, I also plan to get a Mac machine and some iDevices if my android projects become financially viable. But this is currently only a plan. I may also get some gaming consoles (xbox360, ps3) but it's unlikely I'll develop for these machines.
