Olympus LS-12 Linear PCM Recorder
Personally I couldn't be happier with this as a field recording solution and would highly recommend it but find out how it shapes up to others with a very useful review here.
In terms of pricing and suitability, investing in a Macbook is dependant on what types of programs you will be using it for. No ones going to pay top dollar for a laptop just to use Microsoft Office and Facebook. However, as mentioned with top dollar comes top quality and with such a long lifespan, a Macbook Pro is a good long term investment.

Native Instruments: Komplete 8 Ultimate
Although this bundle and others like it may come with a hefty price tag I Guarantee it is well worth the money. The more you spend the better quality might not always be the case but with Native Instruments Komplete bundles, it really is.
