What are the differences between the "Mid-2009" 17-Inch MacBook Pro Core 2 Duo and the "Early 2009" MacBook Pro notebook that it replaced?
Please note that all MacBook Pro models mentioned in this Q&A have been discontinued. However, this Q&A is up-to-date and quite useful for anyone considering one of these notebooks on the used market.
Unlike the 13-Inch and 15-Inch "Mid-2009" models -- which have significant changes compared to the models each replaced -- the MacBook Pro "Core 2 Duo" 2.8 17" (Mid-2009) is quite similar to the MacBook Pro "Core 2 Duo" 2.66 17-Inch (Early 2009/Unibody) that preceded it.

Both models have a black and silver "Unibody" case -- milled from a single block of aluminum -- and include a backlit keyboard, a "no button" glass "multi-touch" trackpad with support for "four finger" gestures and programmable "zones", and 17.0" widescreen (1920x1200) LED-backlit "glossy" displays of similar quality. By default, each has a "glossy" display, but either could be configured with an anti-glare display (with a silver "frame") for an additional US$50.
Both also have a built-in non-swappable battery design that provides an estimated 8 hours of runtime and this battery was not created to be removed or serviced by end users.
Connectivity is the same as well. Both models include AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, Gigabit Ethernet, three USB 2.0 ports, optical digital/analog audio in/out, a "Mini DisplayPort" that supports an external display at 2560x1600, and an ExpressCard/34 expansion slot.
Even internally these models are practically the same. Both use a similar (if not identical) logic board design and 45 nm "Penryn" Intel "Core 2 Duo" processors with two independent processor "cores" on a single silicon chip and a shared 6 MB of "on chip" level 2 cache. Both have a 1066 MHz frontside bus, support 8 GB of 1066 MHz DDR3 SDRAM (PC3-8500), support Serial ATA hard drives, have dual graphics processors -- a NVIDIA GeForce 9600M GT with 512 MB of dedicated GDDR3 SDRAM and an "integrated graphics" NVIDIA GeForce 9400M with 256 MB of memory shared with the system, as well as an 8X DL "SuperDrive".
Ultimately, the "Mid-2009" MacBook Pro model is different only in that it has a faster processor, a larger hard drive, and a lower price. These differences are summarized below:
| MacBook Pro 17" | 2.66 (Early 2009) | 2.8 (Mid-2009) |
