When I got my laptop which is running Windows 8, I decided not to install a 3rd party Start menu just so I would get familiar with working without so I'm prepared if need to help troubleshoot someone's PC running Windows 8.
After using Windows 8 on my laptop for over a month, I have actually got accustomed to not having it, but not exactly how Microsoft would expect. I pinned all the main Applications I use to the taskbar (Firefox, Gimp, Word, etc.) and got in the habit of right-clicking the bottom left for everything else, e.g. control panel, computer management, admin cmd, etc. As for accessories, I use the Run method, i.e. bring up Run, type in notepad, calc, mspaint or what ever other accessory I want and it's straight up.
As for the Metro Start UI, I'm actually not sure when was the last time I intentionally went into a Metro App. One problem I found with Windows 8 Apps is that they don't work with my projector as it has an unsupported resolution, forcing me into desktop mode.
Then again, it would be nice to have the Start menu officially back.
