[Windows Phone 8 Q&A, Help & Troubleshooting] TheGoldrocker:
Here are some answers to the questions you have.

1. The Office suite on WP8 is obviously a stripped-down version compared to the desktop counterparts. However as long as you don't use anything advanced you should be fine. On the phone you will have Word, Excel, PowerPoint and OneNote available. OneNote is especially useful on a phone.

2. It's different. Once you connect the phone to the PC you will find the following pre-defined folders:

- Documents - for Word, Excel, Powerpoint files

- Music - for.. well, music

- Pictures

- Ringtones - for ringtones and notification sounds

- Videos

There is no file manager on the phone itself, however there are apps, which handle files from each of these folders, through which you can rearrange or delete these file types. The system has an API (thus some apps developed as well) for handling new file types like zip, rar, ebook types, etc., which can be registered. You may attempt to open any file type you just downloaded, if an app on your phone is registered to it, it will open the file using it.

Copying the files into the folders I just listed is as straightforward as copying any file using your favorite Windows file manager.

3. Saving email attachments isn't supported out of the box - however you can open them if an app is registered for that file type, and if the app supports saving the file, then you may do that there too (this will save the file to the app's work folder). Once you're in the email app you can only attach photos, but I'm pretty sure you can attach other file types using their own apps and the share button (if any).

4. The short answer is yes. I haven't actually tried this, but I know music ringtones are supported and custom notification sounds are/will be supported with GDR3 (which is an update you can already download if you're a developer or will be getting soon through OTA updates). The way to actually do it is by copying the files to the Ringtones folder, but I think there are some apps, which automate this process (I'm not sure).

5. I'm currently using 2 google IMAP email accounts. I'm pretty sure you should be fine here.

6. Yes, you will have different accounts on the phones, but you don't HAVE to have different ones. I never actually tried sharing accounts, but I know logging in from the same account on several phones is possible, this way you'll get synced contact list, app list, you'll only need to purchase an app once for both of you, and some other benefits. No, you won't necessarily need two different accounts for it on the PC. I use the same account on my phone and on my home (and work) PCs (running Windows 8 and 8.1) and I haven't really seen much syncing between the phone and the computer other than the contact list and account list (email accounts, facebook, twitter, linkedin, microsoft accounts).

7. We're in the same ballpark here, I'm currently enjoying my Lumia 925, I personally think it's a great phone. All of the current devices running WP8 were promised to get 8.1, however we don't really know much details about the update.

People coming from a different major OS generally experience Windows Phones differently, than people coming from feature phones. Android users usually miss the Notification Center and Multitasking, which works differently here (the Live Tiles are your notification center and multitasking works by different rules), and iOS users might miss Siri? Actually I have no idea, since I've never actually owned one.

The sheer number of apps in the store is considerably lower, however there are hardly any apps, which don't have a counterpart in the WP8 store, some are even better than the originals on Android/iOS.

I wish you the best and I hope I helped. Choose wisely ;)
