Ordered basic MB Air... now worried 4GB Ram won't be enough

I do all those things and more, and 4GB is more than enough. I haven't rebooted since buying my system, and it's currently reporting 2.5MB of page outs. Essentially zero.

With Lion on my new 2012 MBA, I'm regularly crossing 4GB according to istat, with similar use to your list. I would however load (fully cached) quite a few HD youtube vids.

Lion does seem to have more of a fondness for RAM. I can't imagine with your light use experiencing any significant problems though, especially as the SSD is even faster this time. I would however always recommend 8GB RAM at this stage if you can afford it.

I use a lot more programs than you simultaneously and never cross 4GB, don't worry. A lot of people say it's good to have 8GB, but most of us just don't need it. The ones who say everybody should get 8GB RAM are running multiple VMs, Photoshop, InDesign and other heavy apps at the same time. They can always benefit from more RAM, but not the light and normal user. I consider myself somewhat normal, I run more than 10 apps, but none use a lot of RAM, so 4 GB is enough (for me).

Lol I only have 2GB in my 2006 iMac, it still works great. It's such an old machine I don't really want to throw more money into it especially with the price of PC2-5300 memory nowadays, but I still love using it.

Ditto. Never lags. You'll be fine.

In the year 2012, buying a machine with only 4GB of RAM is borderline retarded.

Even if you are not using many apps, the OS can use the extra RAM for disk caching.

Those blanket statements never apply to everybody. It's like all the people who say you can't get productive work done on an iPad. You can. But it depends on people's needs and work flows.

Good job ignoring the more important sentence of my post

you will be fine, but in 3 years that will be pushing it. Depends how long you want your laptop to last. The minimum for Mountain Lion is 2gb and i'm sure the next installment will be the same.

And what sentence would that be?

The one where you used an insensitive and offensive slur, or the one where you stated the obvious, and in this case, not terribly relevant point, that more RAM is better?

Sure, 16GB of RAM and 512GB of memory would be nice, but in actual performance, you may not notice any difference at all. In my case, I do a little bit more intensive work than the OP, and most of the time I have 0 Page Outs. The RAM is more than enough.

Thanks everyone. These responses make me feel better about my 4 GB purchase. I am back to thinking I should be just fine.

What a lot of people don't know: When they say "Lion uses so much memory", it actually means "Lion doesn't waste the memory in your computer; if it is there, it will be used because leaving memory unused would be stupid". So you will see that Lion _uses_ all your memory when that is helpful, but it doesn't mean it is actually needed.

Of course you might call Apple and ask them whether your order can still be changed. I would hope if it's not on the UPS truck yet it should be no problem.

I am planning to get 4GB. Tell me, will that be enough if I have Mail, iTunes, iMessage/iChat, Safari, and 10 PDFs open at once? I will be in graduate school so I suspect I will be reading a lot of papers.

I completely disagree with most responses in this thread. Primarily because:

a) the bump to 8GB of RAM is relatively cheap at $100
b) every program (including the OS) will consume as much memory as possible, in order to run as efficiently as possible (meaning, just because your current 4GB system isn't paging, doesn't mean it couldn't benefit from more RAM)
c) 4GB is already considered the minimum, and you can't upgrade to 8GB later on
d) next generation Operating Systems will likely consume less disk space, but more RAM
e) why limit yourself to having x number of applications open and manually 'delegating' memory when you can pay 100 bucks and not worry about it?
f) moore's law - your computer is obsolete _now_. RAM will be cheaper, manufactures of software will take advantage of this and write applications that consume more RAM because it makes developing complex applications easier (I do this all the time)

Paying $100 for the extra 4GB of RAM is a no brainer. What works for you today probably won't work for you in 1 year or less, like it or not.

You'll be fine.

Watch this video, this guy does the same basic stuff as you and it is running solid with 4gb of ram.

are u answering me or the OP? Thanks.

Even browsers are taking up a lot of memory with tabs open today and the system will swap at some point even if it doesn't necessarily need to. I had 4GB in my 2011, but went with 8GB on my 2012. Do keep in mind you can not upgrade later. With 8GB there is no swap used so far, everything is very snappy

From reading your post I also think you will be fine as well, that being said if you open up a couple or several more apps with moderate memory usage you will begin to knock on the door of spinning beach balls. If you feel you might keep adding more opened apps in the future then I suggest you upgrade to a more comfortable 8 gig.

I'm curious to see if 4GB is enough for me. I'm leaving a 2010 17in MBP which I upgraded to 8 on my own.

The problem with ordering from Apple is that upgrades are more expensive due to sales tax. I got my MBA for 1494 from Amazon. It would be 1732 to upgrade the RAM and get it from Apple because sales tax in Texas is high. Add the i7 and you're looking at 1840. Those are expensive upgrades.

Paying $100 for the extra 4GB of RAM is a no brainer. You never know what you might need it for. I'm sure it will also sell better in the future. 4gb is probably way below average in a couple of years from now.

Will I be okay with the 4 GB?

Yes, you will be ok.

But you will always wonder how things could've been with 8GB...

Everybody's saying that the 8GB ram upgrade is a no brainer because it only costs $100 and it's future proof - although that's debatable.

Consider this: would you spend $100 for 4GB more RAM or 1TB external hard drive?

If I can upgrade to 8GB later. - 4GB for now is ok.
but that's not an options for macbook air.

4GB is now a minimum.

On extra ram without a doubt.
