It took too long to write the second part of "Why Sony should acquire Sony Ericsson" and today they just did it!
Now what is next and what should they do?
1- First and foremost, they should get rid of Sony Ericsson brand ASAP! Why? it is obvious ! No one is going to buy a discontinued brand! I think they have done this and that is why they just remodelled Xperia arc to Xperia arc S instead of introducing Nozomi or any other dual core and more powerful phone for now. So we can wait for the Nozomi under Sony brand.
2- Sony needs more market share. During the years SE's market share has vanished. So Sony needs to think big. You might be too young to remember that long time ago HTC was flirting with Sony Ericsson to be bought by them! But now things are changed and HTC has overtaken SE . However, Sony should think about it seriously. Having HTC capacity in the side will bring more market share for them immediately. But it needs too much money as well. Will you lend some money to them?
3- Integrating, Integrating and MORE INTEGRATING. Sony needs to integrate its highly fragmented but rich territories. I think they are on the right path.They just need to make it more quickly. If they can bring Sony's entertainment capabilities such as music, movie, game, ebook, as a sub-ecosystem on the Android almighty platform, It will equip them with a capable weapon to fight against Apple (iOS) and Microsoft (Windows Phone) and also it may help them to differentiate themselves from other Android manufacturers as well.
If Sony could complete at least 2 tasks from the above, you should expect a bigger than Apple outcome!
