While you can always put Windows 8 through its paces by downloading the Developer Preview, there is nothing quite like an absolutely free Windows 8 tablet with decent innards. Microsoft gave away 5,000 such Samsung Windows 8 tablets to developers at last week’s BUILD conference. A few of those developers are apparently so unimpressed that they are now desperately trying to get rid of these gratis tablets for whatever amount people are willing to pay. It turns out that people are willing to pay thousands of dollars.

After failing to keep up with the original Firefox 4 release schedule due to “regressions and sources of instability,” Mozilla had to revise its initial estimates and push back the launch of the stable version to 2011. The open source outfit on Wednesday shipped Mozilla Firefox 4 Beta 8. The actual release of the latest beta comes nearly a month later than originally anticipated.

According to the release notes, the latest build boasts a vastly improved Firefox Sync setup experience across desktop and mobile devices; speed, compatibility and functionality enhancements to WebGL; and a much more polished Add-Ons Manager, which now updates extensions automatically. Furthermore, Mozilla has fixed more than 1,400 bugs.
