Can I use a non "me.com" address to send email with iCloud? I will  be buying an iPad and will want to use iCloud.  However, I want to use a non "@me.com" address to send email from/reply to.  Is this possible when you sign up for iCloud?  Thanks
Using iCloud doesn't necessarily means you'll have to use Mail on iCloud. You can still use your current mail provider to send/receive email on your iPad. Providing you can connect to your current provider using IMAP, Exchange or POP.

You can also create your iCloud account without having a @me.com address. I use my @gmail.com address as my Apple ID to connect to iCloud to sync Contacts, Calendars, etc.
