Re: Migration path from 9630
Well, having never used a Tour, I would probably go with a 9900, or maybe a 9380 (Curve), 9810 (Torch), or 9860 (Torch) if you wanted to go for the touchscreen.
If you need/enjoy a keyboard then go with the 9900 (Bold) or the 9790 (Cheaper Bold). If you wish to keep costs down then you can go for an entry level Curve like the 9320 or 9360.
