And so after contemplating for half a year or more - I finally decided that it's time to get a Mac.
I bought the Feb 2011 model - second hand from Ebay and it looks like to be a good purchase so far (well it's only been few days). To sidetrack a bit - it was quite scary experience buying something expensive from Ebay - it took three weeks for the thing to arrive due to seller being slow in posting, AusPost messed up (or maybe it was the seller's fault all along), the item had to be returned to sender, and then re-sent back to me - just a mess!! But thank God - it's here.
And yes - people were asking why - even today someone at work compares Mac with Dell - which he thinks it's the best value for money. Well, everyone is entitled to their opinions I guess.
To me the reasons for getting a Mac is as follow:
For fun coding things - I have been using Ubuntu. This is especially true for my Ruby and Rails learning. And I am quite happy with it - for dev-ing Linux is certainly way more enjoyable than Windows.
I'm quite excited to see how my experience will be different with Mac OS. As of now, I am looking into settling to an IDE for my Ruby dev - Sublime Text looks to be most likely candidate at the moment - followed by MacVim. A couple of recommendations from friends: TextMate (of course), TextWrangler (BBEdit).
