Windows 10… Now I know what was wrong with Windows 8

I'm sometimes attracted to the shiny new thing, well I at least like to try it for a while on a non-production device.
The very first time I pressed the Start button on Windows 8 I was floored, flummoxed and floundering for familiarity. I liked the idea of it because it felt like Microsoft had brought something to the table that was going to enable some tablet (or iPad as we called them at the time) functionality. Bloggers and journalists described the new Start Screen as "jarring" and while I agreed, I knew I was annoyed by it for a different reason.
I'm a Microsoft Surface Pro 3 user (also had an SP2), so I liked the touch ability but I don't think it made a suitable iPad replacement… it was edging towards a laptop replacement during the 2^nd iteration… and now, Surface pro 3 is a fine laptop replacement. I love this device and I am one of the few "likers" of Windows 8 and I would argue in favour of Windows 8 over Windows 7 especially since the 8.1 release…. With the exception of one big thing…
It was when I spent the last 3 or 4 days using Windows 10 (due for public release mid 2015) that I realised exactly what was wrong with the Windows 8 Start Screen for me.

Have you ever walked into a room and thought 'why did I walk in here, what am I looking for?' Well, that was (is) me with Windows 8 Start Screen. I could be working on a document and decide I need to find something germane, so I press the start key and I am faced with a full screen of live tiles with images of rain, old school friends smiling with their new kitten, news in Syria etc.,,, and now I cannot remember what I came in here for.
If I press escape I can re-read what I was working on and then go back into that live tile room and try to recall what I thought was so important earlier. It was after pushing up to Windows 10 that I realised what I missed about the old windows start menu… continuity & contextual reference-ability.
I think Windows 8 came too soon…. In a way, Windows 10 should have come first (pepper in just a little section of live tiles)… then in a future Windows version from far, far away.. maybe the full start screen would have been more acceptable..?
I look forward to a stable launch of Windows 10 though I am surprised how early they released this preview. Windows 10 should bring businesses the OS they need to move on to from the Windows XP and soon Windows 7 platform.
