There's a lot wrong with it. Let's make a list:
- Metro scrolls sideways. Good for a tablet meant to be held sideways (Surface is 16x9, btw) but stupid on a large screen where you can fit a larger number of applications on the screen. You're also greeted with the "swipe to enter" when you first boot up. Encouraging.
- good luck changing the sizes of those tiles. They're big and blocky and there's no point to that on a desktop. It's not an upgrade or even a sidegrade but a very obvious downgrade from the start menu. It takes longer to find an application than it would with a start menu, offers less as far as options goes, and it takes up the entire screen. What are the upsides again?
- Ribbon style menus are horrible. It's big and blocky and makes the important stuff, like if you were reading a word document, smaller.
- Multi-tasking in Metro is still in the beta stage and no better than Android. Rather ridiculous considering you're talking desktop usage here...
- You can't "close" Metro apps easily, you simply put them in a sleep-but-still-open state. Also, Metro apps are closed by swiping or dragging it to the bottom of the screen. Apparently a small X to click and
actually close doesn't suffice. (this is meant for tablets/phones so the apps open quicker due to the limited resources/computational power but if you're on a desktop with an SSD you don't gain any benefit from this at all outside of a whole lot of alt+ctrl+delete. It's actually worse due to it taking up more resources and becomes an issue if you need to restart the application)
- Mouse and keyboard support in Metro is still poor and apps have issues with M+KB support.
- You get thrown back and forth between Metro and desktop depending on what you're doing/trying to do.
Read this review. If you want to have both a Metro and desktop app open at once then you're essentially switching between two operating systems.
- You still can't resize windows in Metro to the point where you can in the desktop. Setting windows side by side on a workspace and adjusting the sizes to your liking doesn't work in Metro. If you've got a Metro and a desktop app open then you're never going to see them on the same workspace. Have fun toggling.
- Metro apps behave differently and have different options than their desktop counterparts. IE for instance, is different in Metro and the desktop and has different options. For some of the more complicated ones you've got to do it in the desktop and if you want to switch to Metro, or from Metro > desktop, you have to start a new session. Talk about bolting two operating systems together. When you can't get your own software to work the same way in Metro and the desktop then what hope is there for anyone else...
- Everything is big and blocky. If you value your screen real estate then you might as well start planning to make your way to Apple and Linux.
- And the biggest issue of all:
It was never meant for you, the desktop user, in the first place. If you haven't gotten that hint then I don't know what to tell you.
