No gaming for me but I might still stick with the base model.. We'll see. If you've been following previous threads, I mentioned that I recently purchase an iPad 4 (still under my 15 days) and I picked up the MBA yesterday to test out BUT I haven't opened it. I'm still trying to decide if I'm going to keep the iPad or the MBA.. decisions, decisions.
Quite different animals...and both extremely useful in their own right...wipe the memory of spending the cash on the two of them...and keep 'em both
I only have 3 applications (Safari, Powerpoint, and Preview) open, look at how much RAM is being utilized. OS X will put that RAM to use. Notice how there are 0 page outs. 4GB will cause you to constantly page out to the hard drive. Even on a fresh reboot, it will hover above 3GB used without any applications opened.
That's not true...at ALL!!! I've got a core i7/4GB/256GB 2011 Air, no page outs and I've got Chrome open right now (7 tabs), Safari (4 tabs), Mail, iPhoto and I'm doing some recording in Adobe Audition. OSx
will use the memory it has if it needs it and
it's available. If not, OSx is extremely good at memory management and will release from idle applications (or recently closed programs) when necessary to complete the current task. As well, the 2013 MBAs have 800Mb/s NAND storage. While not half as fast as RAM...it's pretty damn close. Paging in/out on this fast of SS storage won't be noticeable in the least if you're not pulling off professional applications (IE: After Effects and available frames). If you
are planning to use professional, creative software for editing video, rendering and transcoding...the MBA might not be the right choice. For audio and still photography though---even the monster D800 Nikon RAW files....manipulation will be incredibly 'zippy' --- even with 'only' 4GB of RAM. As well...with Mavericks, it sounds as though memory management and power/efficiency management are priorities.
While 8GB of RAM is an excellent choice for some, it's not wise for most IMHO.

The critical part of this is how many of those things you do at the same time. I upgraded my MBP from 4 to 8 and quite regularly push past 4gb in use with two or three items on your list going on simultaneously. It's just not always about the individual task demands, but often about the multitasking needs of the user. Just a thought.
How old is your MBP? Does it also have an SSD? How fast? Significant factors when determining configuration of a 'new' machine, especially a MBA vs MBP.
OP---Even doing Window's virtualization/emulation...Parallels has come a LONG way as well helping manage memory. You also have the opportunity to use BootCamp for your other OS'es. This will allow you to devote all 4GB of RAM to each OS while in use.
on the re-sale market, often folks are ignorant to things like RAM and CPU. Storage, they're more aware...but it's folks like
us that value the amount of RAM, Cache size, CPU, GPU, etc...more than the average Joe/Jane. Faster CPU, more RAM...and often, even the bigger SSD will
not return the same value when you pop it up on Craigslist. For further proof, check out 'completed auctions' on eBay for past MBAs.
