I'm going to be using my laptop for teaching in the fall, which means some fairly strenuous 3D molecular rendering, large movies, wireless internet and standard keynote (all simultaneously, of course), as well as the standard day-to-day chores.
I could manage with my ageing G4 AlBook (it continues to run like a champ, but it's a bit slow for the 3D molecular rendering, and it staggers a little with the big animations) but it occurred to me that, even with daily backups, should I have a catastrophic system failure, I couldn't get a replacement in time for the next lecture. So I've decided to buy a new laptop, and keep my venerable G4 AlBook as a backup system.
But I want any new system to be 64-bit, and otherwise as 'future-proof' as possible, so I'm going to hold out for the new memrom-based MBPs. I'm really excited about the possibility of going top-of-the-line for the first time ever. I'm hoping for a system that looks like this:
17" anodized black MBP, with 2.66 GHz Core 2 Duo CPU, 1 GB RAM, a 7200 rpm 120 GB HD, 802.11n, and a blu-ray Superdrive. Should be just over $3k with my educational discount, right?
