Why don't you simply go look at the refurbished inventory on Apple's Online site.
As for which is better for development depends on what you need. An i7 is faster than an i5 which is faster than an i3 all other things being equal. Also, for any processor the higher the clock speed the faster it will be.
For most any use more RAM is also very important, so get at least 4 GBs (more if supported by whatever you buy.) Larger storage is also important - more is always better.
I have checked the online Apple store for refurbished MBAs. But they haven't really mentioned if it is Intel 2nd Gen or 3rd Gen.
Actually I was wondering if a 3rd Gen i5 with lower clock speed like 1.8 can be better than a 2nd Gen i3 with higher clock speed say 2.5.
Honestly, I think you are overcooking it. MBP's are sweet as pie (at least mine is) but if you are that concerned then buy new and get the AppleCare plan. Kappy, correct me if I am wrong here. In short processor cores are only as good as the software using the processor. Some software may only have the capability to max out on 2 cores or even 1 core. I assume this will be your first Apple IFellow?
Yep this will be my first Apple. I am a little low on cash hence was thinking of going with a Apple Refurbished model but with high end specs to start of with iOS Dev.
I came across this:
The only reason is it has a Intel i5 3rd gen processor with 4 GB RAM.
But 128 Flash is a major turnoff. But I can live with that as long as my development work goes good.
I am just wondering if the above model will be good enough.
The Mac Pro 13 inch with i5 & 2.5 GHz is a bit expensive for me.
Honestly you would do better to go with http://store.apple.com/us/product/FD101LL/A/refurbished-macbook-pro-25ghz-dual-c ore-intel-i5
I have heard that the MB-Pro's can also be upgradeded to 16 gigs of Ram, Do-It-Yourself.
However, if you don't need portability then I would say Mac Mini server for sure. $999.
I am running OSX 10.6.8 2.53 GHZ Core 2 duo 4 G's of DDR3 Ram @ 1067 MHZ on this machine. This was my first portable device and I have dropped it on concrete several times obviously it's built well and still runs like day one.
By the way, I am typing slow on here so your windows PC can keep up with me. Good luck
Mac Mini is not an option as I have to make it portable.
I looked at this one as well but choose the earlier one as it had SSD. Storage is not a problem as I have an external drive.
I am stuck here 1.8 with SSD or 2.5 with HDD.
But the Air looks far better compared to the Pro one thing that confuses you when buying Apple products
You are running an Intel 1st Gen processor I dont wan't you to push it else things may fall apart hence relpying late
