Microsoft's Arc Touch ($67.95 list) mouse is about as portable as you can get and adds style to the otherwise plain mobile mouse market. However, the price for such a hot product may make your wallet crawl back into your back pocket.

Unique, portable design; Touch scroll has vibrating feedback; Thumbnail USB has innovative storage on base of mouse; BlueTrack laser technology allows the mouse to be used on a variety of surfaces; Ambidextrous

No browser buttons; Expensive

Even though this is not a new product I find that when it is time to get a replacement I have researched all available options and go back to this model.

Very travel friendly; full functionality; bluetrac and microsoft product seemless integration with os

Lose the USB dongle and the hardware is useless

Microsoft's new Arc Touch Mouse features a travel-friendly design and some clever technical additions to its touch-sensitive scroll tab. Neither of those features makes it better than a full-size desktop mouse, but the Arc Touch Mouse is different enough in its form and in some of its functions that...

Distinct convertible design lets you pack the mouse flat for travel; touch-sensitive scroll tab has vibration feedback and accelerated scrolling features; BlueTrack sensor lets you use the mouse on a variety of surfaces; small USB receiver stays out of the way when plugged in

Expensive; scroll tab occasionally unresponsive; lacks heft compared with standard desktop mice; no thumb-side forward-and-back buttons

The Arc Touch Mouse is the latest in the Arc line-a series of surprisingly design-minded peripherals from Microsoft. The Arc Touch takes the already high-concept line into the stratosphere with a design so innovative that it's almost worth a buy for novelty's sake alone.

Innovative, stylish design; full-size mouse, yet surprisingly portable

Not ergonomic; only two real buttons; not suited at all for gaming

I really like this mouse. I've been using it for a few years now and the only flaw I've found is that when using Photoshop you can't get a precise "click" when scrolling to select a brush size. Other than that it is an excellent product and I use it everyday.

I got this mouse cause I was tired of having the mouse "buldge" in my laptop bags or sleeves. Love the way it folds flat for easy storage. Although the scroll button in the middle is totally flat it vibrates to feel just like a normal mouse scroll which I thought was brilliant.

Folds completely flat for easy storage

Poor handling

Yes, I would recommend this to a friend

Glides Smoothly; Works On Any Surface

Uncomfortable w big hands

an arched touch mouse by Microsoft

sleek design; quick to navigate with

only has one arc setting

Thank goodness my Arc mouse has finally arrived. The last mouse was simply dreadful. Luckily this cutting edge mouse really is a 70 component masterpiece! Why I bought it? I needed a faster mouse, which was/is more compact. It needed to look good too, to compliment my new Ultrabook.

Feels and looks great; clever features

None

Any consumer tech company worth its salt knows that it's all about touch-operation nowadays and that's why Apple unveiled its Magic Trackpad back in the summer of 2010 and Microsoft announced its Arc Touch Mouse not long afterwards, following a series of hints and internet leaks.

Compact; collapsible design; easy to use; fast to setup; compact USB device

Temperamental scrolling; slightly pricey; no side-buttons for thumb
