1. I can't send/receive MS Office files via Bluetooth (a stupid phone with bluetooth and without internet access makes me helpless)
(Also, say i need to present a ppt on a particular PC/laptop, that is connected to a projector, how am i supposed to send the ppt to the PC/laptop?)
That's a disadvantage of WP, you need the Internet for a lot of things... And with the limited functionality of the WP 7.x developer APIs, there's probably not going to be an app for this.
2. I can't capture screen/ munch screen (such a headache not being able to save images of maps or highest scores in my phone)
You cannot capture screen natively on WP 7.x phones, but there is a sideloadable tool to do so. It requires you being able to install app files (.xap) directly from the developer to your phone, but you're going to need a developer license. I think I heard Microsoft opening up the license limitation and letting everyone sideload a couple apps for free, but I can't retrieve the link and I'm not 100% positive it also covers WP 7.x.
3. I can't crop a pic immediately without using an app (need at least a whole minute to crop, save send it via bluetooth to someone)
In the default Camera application on all Windows Phone devices, there is a cropping/rotating function built in. After you snap a picture, swipe left to see that picture, and in the menu bar below, there should be a cropping icon that allows you to do those things.
4. I can't view Youtube videos (says i need to have a flash player)
You don't need flash player at all to view YouTube videos on your phone! You can...
1) Make sure you're visiting m.youtube.com... (or did they cripple YouTube for WP users and pull a
Google on us again?)
2) Download a YouTube application, and my two recommendations are
myTube (paid, and a limited trial)and
MetroTube (completely free with full version on Try, but you can donate to the developer by Buying the app..
5. I can't connect to online people for messaging. (says can't connect to see who's online)
If you're trying to use Facebook chat, you can either use the Facebook app's chat function, or use IM+ (of course there's more, but no need to list them all). The integrated Facebook chat features are crippled now because of Facebook API changes that broke it...
6. I can't stop the sms/whatsapp notification on top (heart ache while playing a game or while doing something else where i wouldn't like to be distracted.)
You can disable this by turning on
Battery Saver from the Settings, which basically tries to save battery and disables Push Notifications in the process. A nifty trick I learned myself
7. I can't make the camera sound mute. (click click click... why won't it mute??
Don't think there's a real, practical workaround for that... You can try installing another camera app and see if that one fits you and doesn't make a shutter sound, or you can just mute your phone's volume when you try to take a picture (which is quite inconvenient, I'm sorry)...
