The upgraded 21.5" comes with an extra 500GB HD not MB :D

If I were to purchase a Mac, I would buy an iMac. I still think it's the best-looking all-in-one around. The only downside is the premium you pay for OS X and Apple engineering. Maybe I'll get one next year when the next minor update comes around.

Say, those Editor's Choice B&W speakers - would they be an appropriate alternative to a soundbar for attaching decent sound to a mid-size TV, while having little floor space to play with? Or is the lack of any kind of sub a dealbreaker? (I'm posting here because the other article's months old.)

@GoldenGuy: Say, those Editor's Choice B&W speakers - would they be an appropriate alternative to a soundbar

I use the B&W Zeppelin as a soundbar, just fits on the shelf underneath our 32in TV nicely. Also handy for charging/playing IPod/Iphone.

Too high a rating for a computer which doesn't run Windows. Mac OS is dominated in technology and compatibility.

You should look at Sony's offerings. I saw an all-in-one in their store with an outstanding screen. I've owned good screens as an amateur photographer but was very impressed with that one. Unfortunately I don't recall the product number.

@Keith: I have the MM-1's. They're great - but as USB connected best for near-field - no real option to use with TV (if that's what your getting at). I have used for both music and movie watching on workstation and would recommend them for sure.

@Hugo: Thanks for review. I'm keen on a all-in-one - but may wait till next year especially if iMac Touch that is rumored

Also - you mention folks would be foolish to choose the upgrade options from Apple directly - are the alternatives available?

I find that they make great facial solaria, but I think that the addition of a small fan at the top of the display would increase its appeal as a hair dryer. Maybe in the next version...

CMSR - You can run Windows on an iMac if you like; either with Boot Camp or just overwriting OS X.

David - DIY is the cheapest option.

Hi chaps, would there be an any chance of doing an article on installing osX on your pc on a virtual drive? I found this but it does seem all pretty complicated.

Would completly understand if you would not want to occur the wrath of apple as i know they hate this hack stuff.

I am happy enough with windows 7, would just like a play with OSX for fun.

I looked at a mac mini but £650 is pricy.

@David: The Zeppelin has Optical input so you can connect your TV to it, that's what I've done anyway..

@David - its ridiculously easy to upgrade an iMac - there are instructions on how to do it in the box. Having said that, when I bought my last one 3 years ago, I called Apple rather than order online, and they did a deal on the memory upgrade, so I was paying the same as ordering through Crucial or Kingston. Nothing to lose by asking!


September 23, 2010, 10:57 pm

Seems to offer real good value... Hehe.


September 23, 2010, 11:53 pm

I just wish they would offer a matte option. I love my 2007 Aluminium iMac band want to upgrade but those glossy screens put me off.


September 24, 2010, 1:20 am

well, I'm using one right now, and it's great! only I do agree wit the USB conections being stupidly placed, having them on the side really wouldnt destroy the design THAT much.

Only, this whole thing woth the superiority of the mac os, i've been using it for all my life, and I must say that recently Apple has gone more for the popular and shoney, than for the real useful and fast. There are a lot of things I love about OS X, but also a lot of things where I think they should be left out, or improved.

If you're going to buy a mac, you should definetely get a desktop version. the laptops are priced at around the same point, they offer less quality, and they stop working great after about two years, whereas the desktop version have so far always worked for up to 5 years for me (although the last year and a half was a pain, with iTunes and Safari not working at all)

wel,, that's my 2 cents ;)


September 24, 2010, 1:22 am

oh, and the glossy screen being a uisance, I couldn't disagree more, I think the screen is wonderfull, and I haven't ever had a problem with reflections or anything, and I use my computer from morning to midnight, so I've tried it in a lot of different light settings.

Good review TR!!!

I have problems with reflections on both the iMac and the 13" MBPs we use at work

2 desktops, and 4 laptops over a 5 year period - they all work as well as each other, wasted money getting Applecare, and laptop batteries as good as when bought first (admittedely, when laptops plugged in, battery always removed). Oh yeah all 6 running as fast as the day I got 'em.

Got rid of last windows computer 2 years ago - MS what?

This size screen would suit me (27" is way to big) for giving Apple a try however the lack of configuration options on the entry level model is annoying particularly no choice of a processor upgrade.

Are components like the proccesor and graphics user upgradeable (as in easily removed, plug/slot in) if you have the machine stripped apart?


September 24, 2010, 1:08 pm


No. Only the Ram is easy to access. The hard drive can be reached but it involves removing the screen. I have done so myself and wouldn't recommend it to someone who isn't used to working on computers. The processor and graphics card you are stuck with. IMO the higher end 21.5: is the one to go for

"height adjustment is conspicuous by its absence" - finally somebody says something about it !

I have the 27" model, but I had to buy a butt ugly (and expensive) Ergotron stand.

Overall it's a nice machine for the price, but I had to open it (voiding the warranty most probably) to put an SSD in mine, and the glossy finish is a problem during certain hours of the day.

I thought the mini display port was an in/out port? So with the appropiate overpriced adaptors you could input another source?


September 24, 2010, 4:41 pm

I'd say the USB ports are perfectly placed... if you use the apple wired keyboard.

I've gotten very used to plugging in temporary devices (USB keys etc.) into my keyboard's hub, and more permanent devices (printers, harddrives) into the rear of my 2009 Mac Mini.

People with the fancy Bluetooth keyboards are fresh out of USB ports though!


September 24, 2010, 4:54 pm

Good review, guys. On looks, though, I still think the G4 iMac with its fully articulating screen was the best combination of looks and functionality they made (and the ad!). I wouldn't mind seeing a return of something like that, but I guess I'm in the minority on this one.

@Kashif Bhatti: Removing the battery when plugging in the laptop isn't an option any more, unfortunately. I wonder how that'll affect battery life.

I have now switched many family and friends to Apple Mac and none has regretted the decision! I use to get constant phone calls from them when they had MS windows based PCs but now I never hear from them, except socially. With advent of Windows 7 things have improved but overall I would suggest all who can afford the little extra stretch to an Apple.

An iMac is the ideal starting point to grow your Apple family followed by an iPod or iPhone and an iPad for use around the home or out and about. Most home users will need no further software purchases to enjoy their machine to the full.

There may be cheaper all-in-one Windows based PCs but none will be as cost effective in the long run. Also you don't need to over spec an Apple as OS X is much less demanding than Windows and does not slow down with age as MS based units.

I'd love to see a 27in G4-style iMac :)
