Okay I loved my first generation MacBook Pro 17, it has served me well for the past 3 years! It has gotten 2 hard drive upgrades, a memory upgrade, as well as a 802.11N wireless card! Franken Mac as I call it was a great system. My new system is just great 4 gig of ram (max of 8 gig) and a 320 gig hard drive (okay this is the first upgrade going to a 500 gig 7200 rpm drive, it fills my need for speed). I have had my new system for about 4 days now and I love the darn thing.
Migrating my settings and apps was a 2 step tasks it seems (migration assistant) did not like moving my Windows virtual machines (okay Apple fix it in snow leopard please, the issue was due to long file names). It also did not move my iTunes files (since it quit before it was finished due to the issue mentioned above).
The new hardware makes virtual box just fly! (I am running Windows 7 as a VM in that), fusion even has more speed as well.
Not to mention iLife 09 is much faster on the hardware as well! I have found on little issue it seems (okay more than one) when I run disk utilities it seems to find a bunch of permission errors, (okay that happens).
