Shanks from appslah.com dropped us a note to talk about his new project, which is a twitter client for Windows Mobile 6.5 which uses Windows Phone 7 like push notifications to not only get you your tweets (in this case mentions) as soon as they arrive, but also saves battery life in the process.
The app has not been released yet, but the video demo above already shows some interesting ideas, such as showing the tweet directly on the screen without interrupting your work flow.
Keep an eye on appslah.com for the eventual release of the app and more info.
Does the elegance of the idea mean Microsoft (and by extension Apple) have got it right regarding push notifications as an alternative to multi-tasking? Let us know your thoughts below.
