2011 macbook pro - worth it?

[The_One]

New to macbooks, want one for the ease of use and portability of one but don't want to splash 2k on a new one.

This decent for £550?

MacBook pro A1286
intel i7 2.0Ghz - TurboBoost 2.9Ghz

Upgraded:

Kingston 16GB RAM
128GB Sandisk SSD (solid state drive) 300+MB/s write, 500MB/s read speed. 100% health
500GB Western Digital HDD replacing superdrive
AMD Radeon HD 6490M 256MB GDDR5 (2014 replacement)

Brand new genuine apple battery

I wouldn't buy that. Get something with a Retina screen, if you want portable go 13".

If this is pre- retina, I really would not.... They look positively archaic compared to anything else. Form factor, screen, pretty sure the older models are being gimped by recent OSX updates, etc.
