The only downside is you don't have multiple third-party firmwares to play with, and you'll never have third-party firmware in fact, because the Ubicom stuff are all close-source. That means no additional features like OpenVPN, CIFS, SSH access, and all those fun things. No cool bandwidth monitoring like what Tomato offers. But if all you need is a stable router, this is a good choice, esp if you have VoIP. This router does QoS for VoIP *very well*.
However, if your laptop has a draft-N wireless adapter, I would highly recommend spending $25 more to get the DIR-655 instead, which is the successor to the DGL-4300 and is draft-N compliant. With draft-N, you get better speed and range. (In comparison, the DGL-4300 is Super-G with max 108Mbps throughput.) The DIR-655 also has a faster processor (Ubicom IP 5160/5170 vs the IP3023 in the DGL-4300 - for performance comparison, look at the "Overall Performance" table on p4 of this document:
