Ok, long story. Well not that long really! I've recently upgraded from my 12" Rev D PB (marketplace baby!) to a 1.67ghz 15" Powerbook with no BTO options. And quite happy I was until yesterday.... When I found out I'm elegible for an education discount. I'm a S.I. manager in a hospital and have on occasion acted as tutor for MSc students, and according to a collegue who has been getting his Mac's with an education discount for years, that is enough to qualify me. Maybe the fact that this is a teaching Trust and I also do a little research (in project management, NOT clinical!!!!) helps, but I had no idea that the discount would apply to me - I was convinced it was student and teachers only. I've since verified this with Apple. So it leaves me a choice.... Do I sell the 3 day of 1.67ghz stock 15" (unfortuately not bought from Apple, but I did get it cheaper) and buy a 1.67ghz 15" with 128MB graphics and the 100GB HDD..... Two things which I'm sure will come in handy, but previously the I couldn't stretch to the extra expense.... not it'll probably only cost me around £50 to do both! (Planning on selling the 15" for around £1350) Am I mad?!?
