If by constantly you mean one time during the last five years, then yea that would be pretty annoying. The vast majority of people have moved onto a new computer or done at least one upgrade. Updates used to be more of a pain, now you just hit purchase and wait for a little bit.
If you haven't upgraded your computer in five years, you should be able to live with a browser than won't be upgraded anymore either. Apple requires 10.7.4 for Safari so you were abandoned by the Mother Ship a long time ago.
