Windows 8 on my PC, Server 2008R2 (courtesy technet subscription)/Linux (PABXiaf)/FreeBSD (pfsense) on my server sitting atop VMWare ESXi 5. iOS 4 something on my iPhone 3G, ICS on my Acer Iconia (everyone at my college got one), and Honeycomb on my HTC Jetstream (got dirt cheap as employee discount). Pissed that I can't upgrade either Android tablets further due to a lack of vendor support.
