The economy was bouncing back from the housing collapse and it's massive ripple effects. The promising tech was Mobile Phones. Everybody wanted a piece, Nokia tried so much with Symbian OS, Samsung came up with Wave OS. Microsoft pushed Windows Mobile which was well liked but wasn't a commercial hit. Firefox and Ubuntu made their mobile OSes, it was a tough competition against the mountains that were Android and iOS. Not only on Software, the hardware tech was mind-bogglingly awesome as well. Nokia made folding phones with keyboard, Blackberry stuck to their game, Samsung followed Apple but later found their uniqueness, Apple is anyway Apple, Microsoft wanted Lumia series to be a big hit poured resources in it but didn't pay off that well. HTC, LG had their ups and downs. After the bad press for Huawei and Google withdrawing their support, Xiaomi and BBK that took the market by storm. Their cheap phones were an instant hit in Asia, Africa. Each pushing the hardware boundaries every so hard to stay in the market, edge to edge display, pop up selfie cameras, high refresh rates, higher megapixels, bigger lenses, 2 cameras, 3 cameras, 5 cameras, glass finishes, chips that'll give desktop computers a run for their money. It was totally wild. My first computer was an IBM PC running Windows 3.0, to many others like me 2010 blew me away is an understatement.
There was Blockchain, Cloud computing became widespread with AWS taking around 70% of the market and incumbence of multi trillion dollar companies were in the news towards the second half of 2010s.
