HTC One (M8) for Windows vs Nokia Lumia Icon vs Lumia 635: specs comparison
Here comes one of the most intriguing Windows Phone devices ever built - the HTC One (M8) for Windows! We're sure that many Windows Phone fans are very excited now that HTC has announced the WP version of its flagship handset, but it goes without saying that there are some other options on the market to be considered before going for this metallic beast.

True, there aren't that many Windows Phone handsets right now to challenge the One (M8) for Windows, but if you're interested in this OS and are a US-based user, you should at least take a look at the Lumia Icon and the Lumia 635. The former is a high-end phone available through AT&T (keep in mind the the M8 for Windows will initially be a Verizon-exclusive), while the latter is a lower mid-range proposition that's available on both AT&T and T-Mobile. However, even though the Lumia 635 is in a very different category specs-wise, we think it does have a place in this comparison, since it can offer very similar functionality, along with a user experience that's not that bad at all.

How do these marvelous smartphones compare exactly? Maybe one has a faster processor, but the other compensates with a bigger battery? All the answers await in the following specs comparison!

Even fandroids must admit it, the One M8 looks better with WP than with Android, no offence.

I'm WP fan and I have to admit it looks worse with WP just because of how software buttons look on WP. I hate them in general but in Sense they are much prettier than WP.

I have to agree with you. Sense look alot better on M8 hardware. Rounded corner phone is kinda miss match for WP. I love those sharp edge designed WP device better. They match the look of tiles

I do side more toward Android. But I also think the M8 looks better with Sense than with WP. I'm not much a fan of its hardware design, but it does go well with Sense.

Beauty is in the eyes of the beholder. No wp8 is not prettier. Ugly to me. Besides Android has no fixed look. I can change a new look every day.
