I have a 2010 2.4GHz Core2Duo with 8GB Ram.

looking at possibly buying a 2012 1.7GHz i5 with 4GB ram

Is this going to be an upgrade to me?

my current macbook in everyday use uses 4.36GB RAM but I know mac expand to use ram as required so not seeing issue here.

Need a portable machine for work to take to customers premises for testing there equipment.

CPU wise the 2012 Air will be much more powerful than your current machine. It also has an SSD, which alone will make the OS feel about 10x faster.

I would assume the RAM would be sufficient if you are sitting around 4GB usage right now. That being said, I don't know your specific use case, so it's hard to make a solid determination as far as memory goes.

Yeah you'll see an improvement in performance, plus it'll be much nicer to cart around as it's thinner/lighter than your C2D MB.

my 2010 has an SSD as well plus a HDD in optical bay.

thanks guys will buy it as not going hang around at the price.

i mainly use chrome/firefox/skype/imessage/thuderbird all at same time.

like said uses 4.36GB ram in normal use.

Will buy.

my 2010 model keyboard has failed keys and can think about repairing later.

light machine is one of main issues.

Best Buy has the base model new 13in MBA (128GB storage with 8GB RAM) on sale for $750. Pretty good deal! Figure on 4-5 years of use....$150 per year or about $12/month. Not bad.

When buying used, consider the remaining useful life of the computer and the true annual cost of ownership. Sometimes (not always), the best deals are the new computers on sale with one year warranty.

Would also consider the condition of the battery. Is it good on the MBA?

The 2013 and newer models have the much better battery life out of the box, so with the 2012, you'd be missing out on that.

If BB has the latest 2015 model MBA at that price, $750, it will do you nicely for a long time. Total annual cost of computing is probably better considering lifetime of ownership. You're looking at just over $107 a year if your 2010 machine is anything to go by (7 ears of life). Using that 2010 as a base, if you're paying more than $220 for that 2012, it will probably be more expensive in the long run, as you'll only get 2 more years out of it. You also get much more for your money on the BB 2015 model...

Thanks guys.

My big problem is funds.

the 2012 air is only £200.
Had new motherboard last year from apple as owner spilt liquid on it.

New higher capacity aftermarket battery available at around £60 (if and when needed).

I love to buy from best buy or where ever but not have the funds.
Also import fee to uk will be high :(

Only thing with the 2012 air is small HDD, but will buy a bigger one later.
May sell my 2010 macbook to fun it.

air should be with me thursday 23rd Fed (my birthday)
[doublepost=1487761011][/doublepost]Also now using my old 2007 17" mabook pro for work again.

Has 4GB ram but only 1.7GB app memory in monitor so the GB in the air should be just fine.
It only has a 2.4GHz core2Duo and runs El capitan (not sierra compatible as no SSE4)
