Yeah, but if I wait (I'm another one who has already decided, but is holding out for a little bit), I can get my new MBP with Leopard...and if I'm lucky, the rumors of new hardware for the MBP will be true and I'll make the leap at that time. I WANT it now, but I don't HAVE to have it right this second. It strains my patience, to be sure, but I figure I can certainly hold out until June-ish.
How long do you wait though? That is the question! But there's always the question of money too.
I looked into the Macs, I really knew what I wanted before I went to the store, saying that, I didn't look into them enough to know there was possibly something new out in June, but then what comes after that?....is it really going to be June?..... is it just a rumor?
In a couple of years it'll be quad-cores all round and we'll be waiting for the quad-core duo!
A friend was in the market for a laptop a couple of months back - portable, needs to work on documents (Word, PDF, Excel), when traveling would like a bit of multimedia (CD, DVD), wireless, Bluetooth for his printer and above all, safe and stable....... When I was helping him choose I was thinking Mac, but could I convince him? Nope!
Instead it was, "do I get this one from Dell, this from Gateway, this from HP.... do I get a £400 one, a £700 one or a nice £1200 Viao? " Being in the same market as him and doing the research I went for the MBP.

this thing is even correcting the spelling in my post! Amazing! and I'm 600 miles away from home in Bonnie Scotland too!
