Before anyone tells me I'm completely insane, hear me out: I was given the 17" MBP new, as a gift from a client. I was going to buy the laptop anyway, but instead had to give £400 to charity to show my company that I wasn't being bribed/used. I also bought AppleCare for the laptop which cost around £280 I think. So I've spent £680 on the machine in total and it still has 1 year, 3 months left of warranty. I've watched a few recent auctions for the same model that I have on eBay, and they've gone for around £1150 *minus fees that'll give me about £1100 to play with.. So, tldr; I will have to spend another £400 to go from my existing 17" to a new 15". I'm a designer and use my laptop for all my work, and could live with the lower resolution (I have an external display) and would just like increased speed, plus the smaller features look tempting *HD iSight and SDXC card reader for instance (I've never used the ExpressCard slot on mine). Cheers Is it worth it?
