In no particular order these things make an MBP better than an E1505
Better Video Card: MBP has ATi X1600 Mobility Radeon, featuring DDR3 memory as opposed to X1400 with DDR2 memory for the E1505
Better Video Card, part 2: Has dual link DVI support so you can drive a 30 Apple Cinema Display. E1505 only has a VGA port what is the maximum external display E1505 can drive? For MBP it is 2560 x 1600
Better Hard Drive: MBP uses Seagate or equivalent, E1505 uses ?? re-packaged as Dell!
Audio: input and output sockets are optical digital (I read earlier this gives lower latency)
Better design: MBP can do dual display or video mirroring or lid-closed driving an external monitor
Install/Restore DVD more convenient to restore your computer to when you got it (not sure what Dell gives you you have to pay for the Windows CD if you want one)
Faster RAM it runs at the speed of the 667 frontside system bus on MBP, on E1505 only at 533MHz
Built-in on MBP, not available on E1505:
MagSafe Power Adapter reduces your chance of accidentally tripping over the power cable and completely trashing your computer
Lithium Polymer Battery better technology
Battery Charge Indicator LED one touch to check the remaining charge in your battery
Apple Remote simpler and easier to use
Built-in webcam
Back-lit keyboard
Ambient light sensors dims screen and lit keyboard automatically
Lighter: MBP is 5.6 pounds; E1505 starts at 6.18 pounds
Thinner: MBP is 1 inch high, E1505 is 1.42 inches high
Faster Network capability: MBP has 10/100/1000 network card, E1505 only has 10/100
6-pin FireWire 400 port, E1505 only has 4-pin FireWire, so you need an adapter to use most FireWire stuff
iLife, Photo Booth and Front Row software
Oh, and one more thing. With the Dell, youre running Windows, dude.
