Should I wait for the M5 macbook pro ?

Is it stupid to wait for the M5, when I can now get the macbook pro with M4? Next fall I will really need the PC to prepare my university thesis... but now I'm studying to take the last exams and I'm tired of reading the slides on my cell phone (even though I've always done it this way until now). I don't know if I'm just impatient or if I have a real need. One option would be to get the basic 11th gen iPad to read slides now and wait for the new MacBooks in September...but I don't know how much it's worth
