First Impressions of the Xperia X1

The X1 has a “curved slide” that angles the screen up, banana-style, when you slide out the keyboard.
The physical keyboard is pretty good, though perhaps not quite up to HTC's standard on the Mogul or the Tilt.
The main buttons have this “X” theme to them, 4 laid out on either side of the way in an inverted diamond shape that I'm not particularly fond of, but it works. The 5 way is a great combination of a touch-mouse (like the Samsung SCH-i780).

Here are the specs, in case you're wondering:

• HSDPA/HSUPA (Quad Band, too)
• WiFi and Bluetooth
• aGPS
• 3.2 Megapixel Camera
• 110 x 53 x 16.7 mm
• 145 grams
• 1500 mAH Battery
• Qualcomm's MSM7200A CPU, 528Mhz (confirmed)
• 800x480 resolution Touchscreen (flush)
• MicroSD for expansion
• MiniUSB for data and chargin
• 3.5mm headset jack for music

The other interesting bit is that SE developed the X1 as a “North American Device.” Most of the design and development work was done in San Diego and has a “North American mindset.” If there was any doubt that Sony Ericsson is aiming this device primarily at the US market, that doubt can now be laid to rest. SE has traditionally done much better in the Asian and European markets with their high-end phones, the Xperia X1 is clearly intended to reverse that trend.
