Six years ago I tried using a Mac exclusively for 30 days. The OS was 10.3, the hardware was a PowerMac G5 and Apple was still the quirky company with a 2% market share.
Five years ago I reviewed my third Mac, the very first Mac mini. In this pre-hackintosh world, Apple was enough of a curiosity that a $499 Mac made a lot of sense. It wasn’t fast, but with a 1.25GHz PowerPC G4 it was quick enough for most of what you needed to do with a Mac back then. Like many Macs, all it really needed was a memory upgrade.
Interest in Apple has obviously gone up since then. Apple’s resurgence coincided with the shift from desktop to notebook computers and thus the preferred entry platform for many into the Mac world were the PowerBook G4, MacBook and MacBook Pro.

The mini continued to receive updates, but its role in Apple’s lineup shifted. The need for an introductory Mac so that users might test drive OS X declined. The mini became a plain old desktop Mac for those who didn’t want an integrated display. For others it was a nice looking HTPC; an Apple nettop before the term existed.
The Mac mini arrived with a bang but was quickly relegated to an almost niche product. It wasn’t Apple TV-bad, but definitely not in Apple’s top 3. The fact that Apple didn’t overhaul the chassis in nearly five years exemplifies the mini’s importance to Apple. Nearly all other consumer targeted Apple hardware gets visual updates more regularly than the Mac mini.
All signs pointed to the mini going the way of the dodo. A couple years ago we regularly saw rumors of Apple killing off the mini entirely. The need for an ultra cheap introduction to OS X had passed. Apple’s customers either wanted a notebook or an iPhone, and if they wanted a netbook Apple eventually addressed that market with the iPad.
While the role of the Mac mini has changed over the years, so has hardware. Originally the mini was 2” tall and measure 6.5” on each side. Small for its time, but bulky compared to what companies like Zotac have been able to do with off the shelf components since then.

In 2005 very few companies were concerned about power consumption, today it’s even more important than overall performance. Intel alone has an internal policy that doesn’t allow the introduction of any new feature into a design that doesn’t increase performance by at least 2% for every 1% increase in power consumption.
What we finally got, after years of waiting, was a redesigned Mac mini:

The 2010 Mac mini looks more like an Apple TV than a Mac. At 1.4” high the new mini doesn’t sound much thinner than the old one until you realize that most of the visible thickness (excluding the pedestal stand) is even smaller than that.

The Apple TV comparison continues when you look at the ports along the back. Apple’s recent infatuation with mini DisplayPort continues, but there’s also an HDMI port on the back of the new mini. Apple thankfully provides a single-link DVI to HDMI adapter in the box for those of you who aren’t hooking the Mac mini up to a HDTV. The HDMI output supports a max resolution of 1920 x 1200 while the miniDP can drive a 2560 x 1600 display with an active miniDP to DVI adapter.

But it’s clear that the HDTV pair is something Apple thought of. The mini is no longer a way to get a taste of OS X, it’s a full fledged HTPC or Apple’s take on the ION nettop.
Internally the Mac mini is pretty much a 13-inch MacBook Pro. You get a 45nm 2.40GHz Core 2 Duo with a 3MB L2 cache (technically it’s the Core 2 Duo P8600). The chipset is NVIDIA’s GeForce 320M, identical to what’s used in the 13-inch MacBook Pro. There’s no dedicated frame buffer. The GPU carves 256MB of main memory out for its own use, which is a problem because the base configuration only ships with 2GB of memory.
The hardware may sound dated since it isn’t using Intel’s Core i3/i5 processors, but we’re limited by space. Apple is unwilling to ship any of its Macs with just Intel integrated graphics. Apple wants a huge installed base of Macs with OpenCL capable GPUs for some reason. And since NVIDIA isn’t allowed to build chipsets for the Core i-whatever processors, Apple would have to go to a three chip solution in order to have a Core i-whatever, Intel’s associated chipset and an AMD/NVIDIA GPU. In size constrained products (e.g. 13-inch MacBook Pro or the new Mac mini), Apple prefers to use a Core 2 generation CPU and a single chip NVIDIA IGP to fit the form factor and GPU requirements.
Styling and UseThe mini’s design is cohesive with the rest of Apple’s lineup. The unibody aluminum construction is less functional in a stationary desktop compared to a notebook that has to be rugged, but it’s nice to look at nonetheless.
At the front of the Mac mini is the opening for the internal slot loading 8x SuperDrive. The drive can write to DVD±R discs as well as dual layer variants. DVD±RWs and CD-R/RWs are also supported. There's no option for a Blu-ray drive.
Like all Macs, there’s no eject button - for that you’ll need an Apple keyboard (not included). There are actually no input devices included in the purchase price, so expect to add another $120 if you want an Apple keyboard and Magic Mouse ($140 if you want them to both be wireless). There’s no remote included either, although Apple’s IR remotes do work with the mini.
The power button is around back, as well as the power connector. The power supply is internal so all you have on the outside is a single white cable with no power brick.
Gigabit Ethernet, FireWire 800 and four USB 2.0 ports line the rear along with the miniDP and HDMI outputs I mentioned earlier. A new addition is the SDXC slot on the back.
The mini has a single internal speaker but you also get digital/analog 1/8” line in and line out jacks. If you’ve got an iPhone headset, just plug it into the headphone minijack and you’ll get both headphone and mic functionality.
The Mac mini ships with 802.11a/b/g/n support but has no external WiFi antenna. The antenna is located in the base of the unit, directly underneath the removable access cover.
The internal antenna behaves virtually identically to a notebook’s WiFi. In fact, I got very similar WiFi performance out of the Mac mini as I did with this year’s MacBook Pro. With a good access point, getting reception at around 60 feet away through walls in a house wasn’t a problem.
The only issue I had with the Mac mini’s WiFi was when I placed the unit in my theater room. The theater is enclosed in two layers of drywall and has a small closet with a metal equipment rack in it. With the mini in the middle of the equipment rack, surrounded by amps and a pre-processor, I couldn’t get more than 1.2MB/s to the nearest access point which was less than 30 feet away but outside of the room. While that’s still enough bandwidth for surfing the web, it’s not enough to stream HD video from a networked file server.
I wouldn’t fault the Mac mini’s WiFi however. I was simply asking too much of it. But keep this in mind if you don’t have ethernet running to a similar setup. Thankfully, I do have ethernet going to the rack and thus it wasn’t an issue.
