Microsoft has itself, to some extent, crippled Windows 10 Mobile by giving slower hardware in Lumia smartphones [COMPACTIDEA]

Recently upgraded my Lumia 640 XL to Windows 10 Mobile. Not everything is good. Overall it has been a big step backward. If I could [unfortunately I can't], I would definitely go back to Windows Phone 8.1 [Lumia Denim] in a heartbeat. My phone used to be so fast on 8.1 Denim. My Lumia has become so slow after upgrading the OS. It's almost useless now. Its slowness irritates. Fuck Microsoft. Plus, and this is very important, Windows 10 Mobile isn't better in every sense than Windows Phone 8.1 [Lumia Denim]. The former has lost some features of 8.1 Denim, and some features have become worse due to changes [note that this isn't about being slow due to dated hardware specifications]. Sure, Windows 10 Mobile has many new features, but what's the use of features if the hardware is so slow? It doesn't feel so on 8.1 Denim, but it clearly shows on 10 Mobile. The full power and potential of Windows 10 Mobile simply can't be realized/used because the phone hardware is so pathetically slow. In this sense Microsoft itself is responsible, to some extent, for me not being able to take advantage of Windows 10 Mobile. Also, there is some very good stuff in the Store, but again, I just cannot use any of it due to the deficient hardware. On 8.1 Denim, at least everything ran fast and nothing irritated me.
