This logic is flawed.
How is it a bad deal financially? Compared to what? A PC laptop with more recent hardware in? If so, then this isn't an even comparison because the other machine
Is not a Mac.
A Mac is:
1) Well designed and built to last
2) Power efficient
3) Equipped with Snow Leopard
4) Comes with some pretty decent software to get you started (iLife etc)
5) Backed up with top drawer technical support for both hardware and software.
None of these things have
anything to do with featuring the latest hardware but are all exclusive to the experience of buying a mac.
A PC is:
1) Possibly well designed, but possibly also just plastic crud
2) Not power efficient if it's using the i7 and discrete graphics
3) Comes with Windows, for better or worse
4) At best comes with trial-ware, at worst comes with crap-ware.
5) Technical support is a lottery but chances are you'll end up talking to someone on another continent for whom English is a 2nd language.
I'd hate to have to go back to Windows again.

The fact is if you want a Mac, you can either pay Apple's prices, build a Hackintosh or buy second hand. Those are your choices, simple as that
