I love my Atrix. The display size is large enough to do what I need to yet it's small enough to still fit in my pocket w/o feeling like I've got a massive lump in it.
Atrix: 5.00 in? = 4.64 x 2.50 x 0.43
Nexus: 4.98 in? = 5.33 x 2.67 x 0.35
Overall they are the same volume. The Atrix is thicker. The Galaxy Nexus weighs exactly the same (4.76 oz). If the Nexus is a massive lump, is the Atrix a massive lump as well?
The Atrix 2 at 5.07 in? (4.96 x 2.59 x 0.40) is bigger than a Galaxy Nexus overall. The Atrix 2 at 5.18 oz weighs more than the Galaxy Nexus, LG Nitro HD, Infuse, and Epic 4G Touch.
So I'd love ICS, but I'm not holding my breath for it..
The Atrix is just too little to display the new Ice Cream Sandwich components like Recent Apps, etc. Even if someone found a way to get ICS on the Atrix, would you want it?
That is the rumor why we may not see ICS on the RAZR any time soon. 4.3" low def is not going to be pretty. ICS needs HD and screen space.
The Galaxy Nexus is the same weight and volume as the Atrix but has the bigger screen and HD that ICS really needs.
See the spec comparison of the
Atrix, Atrix 2, and Galaxy Nexus.
Also see the
Phone Comparison for specs on a dozen recent phones.
But if your Atrix does everything you need, do you need to get a new phone? And really what it comes down to is what feels right to you. Phones are like shoes. Get what fits you.
