Ubuntu 8.04, a.k.a. Hardy Heron, Alpha 5 hit the wires late Friday evening. I downloaded my copy around 8pm Orlando local time (EST). After super and kitchen duty I sat down and ran the release around the four systems I have at home to see how it worked.
It's definitely an alpha, and a very raw alpha. Unlike my experiences with 7.04 and 7.10, the testing of the 8.04 alphas has been much rougher, so rough in fact that I probably won't upgrade to 8.04 until the final release. And that's assuming that openSUSE 11 is another disaster like 10.3 was.
The four test computers consist of two desktops and two notebooks. All the computers are 32-bit, and only one, the M685 Gateway, is a dual core (Intel Core Duo). All the computers run Linux, and three of the four dual-boot between Windows XP SP2 and Linux. The notebooks dual boot between WinXP and openSUSE 10.2, and the desktops run Ubuntu 7.10. All operating systems are running with the latest patches from their respective suppliers.
