I was planning to upgrade my Lenovo Netbook to Dell Laptop in recent future. It had Windows 7. My needs were browsing, emails, MS Office and little bit of my experiments with various applications. There was no urgent need to move away from netbook.
Mean while, I bought Lumia 520 in 2013 and recently upgraded to Lumia 640 XL. I realized that I am on right path and very soon need devices which sync with each other to reduce data duplication. Windows OS was perfect solution and hence I decided to wait for Windows 10.
On 29th July evening, I started downloading Windows 10 Upgrade as I reserved it earlier. I could not download it overnight due to lower download speed at my home. Hence continued it on 31st. Finally, it downloaded everything and started upgrade process.
The upgrade process was very smooth and did not need technical knowledge at all. It got upgraded overnight and I logged in to my netbook early morning. I am loving the new experience. Now, I am waiting for my Lumia to get upgraded to Windows 10.
I hope, I will not change my devices now unless any hardware fails.
