I have been using a Windows Phone 7.5 (HTC Radar) for about 9 months before I made the switch to iPhone 5 yesterday. Since the switch (I changed the carrier also, from T-Mo to VZ), I have enjoyed and cherished every single minute. The vastly improved UI, large number of apps, and much faster network speed represent a revolutionary improvement in user experience. However, I did find myself missing a few things from the crappy Windows Phone. The HTC Radar itself is solidly built phone, a well made, stable piece of hardware. I believe all the frustrations with this phone are rooted solely in the OS.
I will save my rant against the poor OS. here are the a few things I actually liked (unfortunately they are not available on iPhone)
1. native integration of social network/email accounts with Contact. On the Windows Phone, the Contact not only contains the basic info such as phone #, address, and name, the Contact function also pulls in (after your setting up respective accounts of course) your contacts' profile information from social networks such as LinkedIn, FB, and Twitter. Therefore in Contact, you get a much fun glimpse of a person's background (updates, career, and photos). Also, it comes very handy when your original entry only has an email address, and then Contact includes the person's phone number disclosed on LinkedIn, or the other way around. Very useful when you want to reach out to someone you just acquainted with.
2. Chinese pinyin input on Windows Phone is so much more intelligent than the one on iPhone. I can get most of the more recent and trendy phrases correct the first time, on the Windows Phone. Also it remembers my personal phrases and words very faithfully. I have none of that on the iPhone. iPhone's input seems to have a tiny dictionary, even some of the most traditional idioms are included.
3. Office apps: needless to say, for work, a native office app and respective file formats (doc, xls) can be transferred seamlessly to my work desktop.
I will save my words on how wonderful iPhone 5 is, as I will save my anger to say what crappy job MS has done in its mobile phone OS.
