Under the bonnet, the F900 is driven by a Samsung SC3 6410 processor running at a reasonably sprightly 533MHz, backed up by 128MB of RAM. The phone isn't what we'd describe as lightning fast, as sometimes it seems to struggle a bit when you've got multiple apps running. However, for most day to day tasks like browsing the web and watching the odd video it's plenty fast enough. Along with the 128MB of RAM, there's also 256MB of built-in storage and this can be boosted using microSD cards.
When it comes to web browsing, you'll have to download the Opera browser yourself as by default Acer leaves you reliant on the woeful built-in Internet Explorer. However, once you do load up Opera you'll find that the handset delivers a pretty good browsing experience when running on either Wi-Fi at home or on HSDPA when out an about (speeds of up to 7.6mbit/s are supported on the latter).
The handset also has quad-band support for GSM and triband for 3G so you shouldn't have much trouble using it to make calls or connect to the web on your travels. As with most of today's smartphones the F900 also has onboard GPS. No navigation software is included, but Acer has pre-installed Googlemaps. The GPS chip worked perfectly with this and was quick to lock on to satellites from a cold start. Another neat addition is the onboard FM tuner. It's not RDS enabled so it doesn't pick up station names, but you can store stations as presets and add names to them there. The F900 also has a 3.2-megapixel camera with autofocus and an LED flash, but the shots it takes are run-of-the-mill cameraphone quality. That's to say edges tend to look a tad on the smudgy side.
