no not at all i use them for different uses my iphone is for work calls, texts, calendar,notes,email(personal and work) with a few games here and there my iphone is on me 24/7.
my ipad is for entertainment i will use it with a bluetooth keyboard as a laptop replacement on occasion but its usually used for web browsing, media, gaming, email, word processing.
see for me the ipad is nicer to use in email because of screen size but plain and simple it can never affect my phone use because its not pocketable and it has different uses for me. they compliment each other perfectly in my use. I really want a sync between them for like notes or web browsing like the hp slate and pre 3 will have i want to be working on a project on my ipad tap my phone to it then be on the go and vice versa that would be amazing!
