UG - Motorola Atrix 4G

I have to admit that I am in love with the concept of the Motorola Atrix 4G. Just look at these specs/features:

• Dual core 1GHz Tegra 
• 1 GB RAM
• 4" screen
• Android 2.2 (Wish this was 2.3)
• Battery: 1930 mAh
• Supports 48 GB memory
• Fingerprint login security
• Webtop when docked with laptop or full keyboard/monitor/mouse
• Webtop allows saving state
• Full Firefox in Webtop

If you haven't checked it out, go hit Google and see some of the demos of this thing, especially when it is docked in the laptop or HDMI/keyboard/mouse dock. I love the UI Motorola created for docking called Webtop. Somehow they got full Firefox running and the thing automatically saves state when you pull it out of the dock. 

I only have two concerns with this device. The first one is that it is for AT&T only right now, but I am hoping that changes, but I am not going to bag on one carrier or another, but AT&T doesn't do well in my area. My other concern has to do with Motorola continuing the trend of how this thing can be used. I don't want to buy this phone and all the accessories to find to out that future phones from Motorola won't support the dock concept. I hope these features get added to all their high end phones and that way I can upgrade without having to re-buy everything. Those are the only things that really hold me up about buying this, but I love the idea of this phone.
