I'm also not a fan of metro design.
Neither was I, it looks dull compared to Windows 7. I particularly dont like the tiny icon in the middle of a massive tile; Whats the point of that?
That said though, when I moved from IoS 6 to Ios 7 on my iTouch, I hated the new flat design, but now I wouldn't go back.
The Metro style is beginning to look less jarring. I just wish they'd give a consistent look to everything in Windows 10, not a bit of this and a bit of that. It looks half finished, and that's a shame because otherwise it seems very stable and responsive.
