Can't see anything from this marketing/PR bullshit that gives me a reason to switch. In fact, with my recent digitizer touchscreen laptop purchase, I had the choice between putting Windows 7 or Windows 8 on it and after using W8 on my older laptop for just over half a year, I still decided to stick with Windows 7. The icons are just the right size, even for a touchscreen, all the same power saving features are there, as is TRIM and all the SSD functions which I needed. The closest actual feature to an improvement I saw on this so called "news article" was the texture streaming thing used to render Windows 8's graphical user interface -- this is a non-issue for me anyway since I disable Aero and any other fancy visual effects to save resources on all my Windows 7 machines, regardless of how good my PC/laptop is (I do the same thing with my gaming rig to stop it wasting VRAM).
One thing is for sure -- Microshaft better come up with a REAL successor to Windows Vista, and fast. Yes, I said Vista. Windows 7 was Vista v2.0 (with minor tweaks like TRIM support, upgraded driver stack etc), Windows 8 is Vista v3.0 (with a different interface and slightly better multithreading support). I will NOT buy another excuse of an OS that's merely another service pack for Vista again, regardless of how cheap it will be (the only reason I bought 8 was because it was so cheap). I want an entirely new kernel running in a driverless, fully hardware accelerated environment. Until they do that, they have no chance of ever beating Android, iOS or any other operating systems found on tablets, phones etc and I will have no interest of ever paying them again for another re-hashed operating system.
