I got my Droid 2 Global last week and my only qualm is that Motorola and Verizon have essentially engaged in false advertising with respect to global roaming capabilities. The tech specs on both websites list the device as quad-band GSM and tri-band UMTS...but VZW has restricted use of the 850/1900 bands, effectively making the phone dual-band GSM (900/1800) and single-band UMTS (2100).
Basically what this means in practice is that for any country in the Americas, from Canada on down to the southernmost tip of South America, use of foreign SIM cards (and consequently, cheap local rates) will not work. And of course it also means the device will not work on AT&T or T-Mobile here in the US. We have to wait until someone hacks the radio firmware to unrestrict the 850/1900 MHz bands.
The default MotoBLUR launcher/homescreens are incredibly laggy, I agree. However I use LauncherPro instead which takes care of the lag...it's super fast. I'd recommend using that, if you aren't already familiar with it. Free in the market and lots of customization options.
