I'm saving for a new macbook or macbook pro to buy after leopard comes out. I have an older Thinkpad T42 with a 1.7ghz processor and 512ram. I wanted to upgrade it with components I could transfer to a macbook. So I wanted to get a 250gb 5400 Scorpio HD, and the 4gb ram kit (with the hope that there will be a future santarosa macbook which can address 4gb of ram). My question is whether that ram will work in the older T42 with the Pentium M processor? Thoughts on my plan-this will tide me over until I can afford one-I was planning on adding these upgrades to a macbook regardless-so I at least get to use them until then.
